使用maven搭建ssm框架环境

1.前言

因为经常换环境，在搭ssm框架的时候老是出错，所以记录一下最近搭建的环境，以供参考。

本文讲解如何使用maven搭建ssm框架，并能用于简单的登录注册。

IDE：IDEA，JDK版本：1.8，数据库：mysql5.7  　　启动方式：tomcat

首先创建一个简单的数据库表，用于保存用户名和密码，id是主键，如图：

使用maven搭建ssm框架环境

然后创建一个maven的web工程，先上目录结构：

使用maven搭建ssm框架环境

在java中总共有五个包：

  1. controller：放置控制器，在控制层控制逻辑业务跳转的类文件。
  2. dao：dao层的接口及其实现类都放在这个包下，其中包含generator逆向生成的类
  3. bean：存放generator逆向生成实体类
  4. test：使用逆向时需要的测试类
  5. service：业务层的接口与实现类放在这个包下，包含具体业务逻辑。

2.maven工程导入依赖

下面是需要在pom.xml文件中添加的依赖，可能部分jar包多余，但是本项目不冲突：

3.配置文件

在src/main/resources下新建几个基本的配置文件：

使用maven搭建ssm框架环境

其中，mapper文件夹存放generator逆向生成的mapper配置文件；

db.properties是放置数据库以及数据池的数据：

driver=com.mysql.jdbc.Driver

#在和mysql传递数据的过程中，使用unicode编码格式，并且字符集设置为utf-8

url=jdbc:mysql://127.0.0.1:3306/ssm?useUnicode=true&characterEncoding=utf-8

user=root

password=root

#password=123456

minIdle=50

maxIdle=45

initialSize=5

maxActive=100

maxWait=100

removeAbandonedTimeout=180

removeAbandoned=true

timeBetweenEvictionRunsMillis=60000

testWhileIdle=true

testOnBorrow=false

testOnReturn=false

log4j.properties是日志的相关配置：

# Global logging configuration

log4j.rootLogger=DEBUG, stdout

# Console output...

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

ApplicationContext.xml是Spring的配置文件：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:context="http://www.springframework.org/schema/context"

       xmlns:p="http://www.springframework.org/schema/p"

    http://www.springframework.org/schema/util

    http://www.springframework.org/schema/util/spring-util-4.0.xsd">

    <!--注解扫描-->

    <context:component-scan base-package="itle.service"></context:component-scan>

    <!--数据源连接池-->

    <context:property-placeholder location="classpath:db.properties" />

    <bean id="dataSource"

          class="org.apache.commons.dbcp.BasicDataSource"

          p:driverClassName="${driver}" p:url="${url}" p:username="${user}"

          p:password="${password}" p:minIdle="${minIdle}" p:maxIdle="${maxIdle}"

          p:initialSize="${initialSize}" p:maxActive="${maxActive}"

          p:maxWait="${maxWait}" p:removeAbandoned="${removeAbandoned}"

          p:removeAbandonedTimeout="${removeAbandonedTimeout}"

          p:testOnBorrow="${testOnBorrow}"

          p:testOnReturn="${testOnReturn}"

          p:validationQuery="select 1"

          p:testWhileIdle="${testWhileIdle}"

          p:numTestsPerEvictionRun="${maxActive}"

          p:timeBetweenEvictionRunsMillis="${timeBetweenEvictionRunsMillis}">

    </bean>

    <!--sql的映射文件配置-->

    <bean id="sqlSessionFactory"

          class="org.mybatis.spring.SqlSessionFactoryBean"

          p:dataSource-ref="dataSource"

          p:configLocation="classpath:mybatis-config.xml"

          p:typeAliasesPackage="itle.bean"

          p:mapperLocations="classpath:mapper/UserMapper.xml"></bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"

          p:basePackage="itle.dao"></bean>

    <!-- 事务管理器 -->

    <bean id="transactionManager"

          class="org.springframework.jdbc.datasource.DataSourceTransactionManager"

          p:dataSource-ref="dataSource">

    </bean>

    <!-- 事务注解的支持 -->

    <tx:annotation-driven

            transaction-manager="transactionManager" />

    </beans>

mybatis-config.xml是mybatis的配置文件：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

        "http://mybatis.org/dtd/mybatis-3-config.dtd" >

<configuration>

    <plugins>

        <plugin interceptor="com.github.pagehelper.PageHelper">

            <property name="pageSizeZero" value="true"/>

            <property name="reasonable" value="true"/></plugin>

    </plugins>

</configuration>

SpringMvc.xml是springmvc的配置文件：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xmlns:aop="http://www.springframework.org/schema/aop"

       xmlns:context="http://www.springframework.org/schema/context"

       xmlns:mvc="http://www.springframework.org/schema/mvc"

       xmlns:p="http://www.springframework.org/schema/p"

       xmlns:tx="http://www.springframework.org/schema/tx"

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd

        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd

        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">

    <!-- @Controller注解扫描 -->

    <context:component-scan

            base-package="itle.controller"></context:component-scan>

    <!-- 注解驱动:

           替我们显示的配置了最新版的注解的处理器映射器和处理器适配器 -->

    <mvc:annotation-driven ></mvc:annotation-driven>

    <!-- 配置视图解析器

   作用:在controller中指定页面路径的时候就不用写页面的完整路径名称了,可以直接写页面去掉扩展名的名称

   -->

    <!--配多视图解析器 -->

    <bean id="contentNegotiationManager"

          class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">

        <property name="mediaTypes">

            <map>

                <entry key="html" value="text/html;charset=UTF-8"></entry>

                <entry key="json" value="application/json;charset=UTF-8"></entry>

                <entry key="xml" value="application/xml;charset=UTF-8"></entry>

            </map>

        </property>

        <property name="defaultContentType" value="text/html"></property>

    </bean>

    <bean

            class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">

        <property name="contentNegotiationManager"

                  ref="contentNegotiationManager"></property>

        <property name="viewResolvers">

            <list>

                <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"

                        p:suffix=".jsp"

                        p:prefix="/WEB-INF/jsp/"></bean>

            </list>

        </property>

    </bean>

</beans>

接下来是web.xml的全局配置：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

  <display-name>ssm3</display-name>

  <welcome-file-list>

    <welcome-file>index.html</welcome-file>

    <welcome-file>index.htm</welcome-file>

    <welcome-file>index.jsp</welcome-file>

    <welcome-file>default.html</welcome-file>

    <welcome-file>default.htm</welcome-file>

    <welcome-file>default.jsp</welcome-file>

  </welcome-file-list>

  <!-- 加载spring容器 -->

  <context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>classpath:ApplicationContext*.xml</param-value>

  </context-param>

  <listener>

    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

  </listener>

  <!-- springmvc前端控制器 -->

  <servlet>

    <servlet-name>springMvc</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <init-param>

      <param-name>contextConfigLocation</param-name>

      <param-value>classpath:SpringMvc.xml</param-value>

    </init-param>

    <!-- 在tomcat启动的时候就加载这个servlet -->

    <load-on-startup>1</load-on-startup>

  </servlet>

  <servlet-mapping>

    <servlet-name>springMvc</servlet-name>

    <url-pattern>*.action</url-pattern>

  </servlet-mapping>

  <!--编码设置-->

  <filter>

    <filter-name>characterEncodingFilter</filter-name>

    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

    <init-param>

      <param-name>encoding</param-name>

      <param-value>UTF-8</param-value>

    </init-param>

    <init-param>

      <param-name>forceEncoding</param-name>

      <param-value>true</param-value>

    </init-param>

  </filter>

  <filter-mapping>

    <filter-name>characterEncodingFilter</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>

</web-app>

到此，ssm的环境基本算是搭建成功，接下来是要编写java实体代码。

4.Genarator自动构建代码

首先是genarator.xml文件，用于逆向自动生成dao和bean以及mapper的映射文件，需要改动路径的部分都用注释标明，代码如下：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE generatorConfiguration

        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"

        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>

    <context id="testTables" targetRuntime="MyBatis3">

        <commentGenerator>

            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->

            <property name="suppressAllComments" value="true" />

        </commentGenerator>

        <!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->

        <jdbcConnection driverClass="com.mysql.jdbc.Driver"

                        connectionURL="jdbc:mysql://localhost:3306/ssm" userId="root"

                        password="root">

        </jdbcConnection>

        <!-- <jdbcConnection driverClass="oracle.jdbc.OracleDriver"

            connectionURL="jdbc:oracle:thin:@127.0.0.1:1521:yycg"

            userId="yycg"

            password="yycg">

        </jdbcConnection> -->

        <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer，为 true时把JDBC DECIMAL 和

            NUMERIC 类型解析为java.math.BigDecimal -->

        <javaTypeResolver>

            <property name="forceBigDecimals" value="false" />

        </javaTypeResolver>

        <!-- targetProject:指定生成PO类的位置 -->               <!--改#####-->

        <javaModelGenerator targetPackage="itle.bean"

                            targetProject=".\src\main\java">

            <!-- enableSubPackages:是否让schema作为包的后缀 -->

            <property name="enableSubPackages" value="false" />

            <!-- 从数据库返回的值被清理前后的空格 -->

            <property name="trimStrings" value="true" />

        </javaModelGenerator>

        <!-- targetProject:指定sql文件mapper映射文件生成的位置 -->   <!--改#####-->

        <sqlMapGenerator targetPackage="mapper"

                         targetProject=".\src\main\resources">

            <!-- enableSubPackages:是否让schema作为包的后缀 -->

            <property name="enableSubPackages" value="false" />

        </sqlMapGenerator>

        <!-- targetPackage：指定dao接口m生成的位置 -->            <!--改#####-->

        <javaClientGenerator type="XMLMAPPER"

                             targetPackage="itle.dao"

                             targetProject=".\src\main\java">

            <!-- enableSubPackages:是否让schema作为包的后缀 -->

            <property name="enableSubPackages" value="false" />

        </javaClientGenerator>

        <!-- 指定数据库表 -->

        <!--         <table tableName="items"></table> -->

        <table tableName="user"></table>                     <!--改#####-->

        <!--         <table tableName="orderdetail"></table> -->

        <!--         <table tableName="user"></table> -->

        <!-- <table schema="" tableName="sys_user"></table>

        <table schema="" tableName="sys_role"></table>

        <table schema="" tableName="sys_permission"></table>

        <table schema="" tableName="sys_user_role"></table>

        <table schema="" tableName="sys_role_permission"></table> -->

        <!-- 有些表的字段需要指定java类型

         <table schema="" tableName="">

            <columnOverride column="" javaType="" />

        </table> -->

    </context>

</generatorConfiguration>

配置genarator.xml之后要编写测试类编译生成相关配置类，在itle/test中新建一个类StartServer

import java.io.File;

import java.util.ArrayList;

import java.util.List;

import org.mybatis.generator.api.MyBatisGenerator;

import org.mybatis.generator.config.Configuration;

import org.mybatis.generator.config.xml.ConfigurationParser;

import org.mybatis.generator.internal.DefaultShellCallback;

//逆向生成映射文件

public class StartServer {

    public void generator() throws Exception{

        List<String> warnings = new ArrayList<String>();

        boolean overwrite = true;

        File configFile = new File("src\\main\\resources\\genarator.xml");

        ConfigurationParser cp = new ConfigurationParser(warnings);

        Configuration config = cp.parseConfiguration(configFile);

        DefaultShellCallback callback = new DefaultShellCallback(overwrite);

        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,

                callback, warnings);

        myBatisGenerator.generate(null);

    }

    public static void main(String[] args) throws Exception {

        try {

            StartServer startServer = new StartServer();

            startServer.generator();

        } catch (Exception e) {

            e.printStackTrace();

        }

    }

运行这段代码，刷新项目，会dao、bean、mapper三个包中生成相应类，所以这3个包我们是不需要去管的。

5.编写业务层

在service包下新建一个接口 IUserService

import java.util.List;

import itle.bean.User;

public interface IUserService {

    public boolean findUserByNameAndPwd(User user) throws Exception;

    public boolean register(User user) throws Exception;

}

再新建一个相应的实现类 UserServiceImpl

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import itle.dao.UserMapper;

import itle.bean.User;

import itle.bean.UserExample;

@Service

public class UserServiceImpl implements IUserService {

    @Autowired

    private UserMapper userMapper;

    //根据对象查询

    public boolean findUserByNameAndPwd(User user) throws Exception {

        UserExample example = new UserExample();

        List<User> list = userMapper.selectByExample(example);

        for(User u:list) {

            if(u.getUsername().equals(user.getUsername())&&

                    u.getUserpwd().equals(user.getUserpwd())) {

                return true;

            }

        }

        return false;

    }

    //插入一个对象的数据

    public boolean register(User user) throws Exception {

        int i = userMapper.insertSelective(user);

        if(i>0) {

            return true;

        }

        return false;

    }

}

6.编写控制层

在controller包中新建一个类 UserCtroller

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import itle.bean.User;

import itle.service.IUserService;

@Controller

public class UserCtroller {

    @Autowired

    private IUserService userService;

    //登录

    @RequestMapping("/login")

    public String loginqw(User user) throws Exception{

        if(userService.findUserByNameAndPwd(user)) {

            return "success";

        }

        return "login";

    }

    @RequestMapping("/indexReg")

    public String indexreg() {

        return "register";

    }

    @RequestMapping("/index")

    public String indexLog() {

        return "login";

    }

    //注册

    @RequestMapping("/reg")

    public String register(User user) throws Exception{

        if(userService.register(user)) {

            return "success";

        }

        return "register";

    }

}

7.jsp页面

需要用于登陆注册的页面

在webapp/WEB-INF下新建一个jsp文件夹，用于管理jsp页面，在文件夹下新建login.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"

         pageEncoding="UTF-8"%>

<!DOCTYPE html>

<html>

<head>

    <meta charset="UTF-8">

    <title>Insert title here</title>

</head>

<body>

<h2>登录页面</h2>

<form action="login.action" method="post">

    用户名：<input type="text" name="username" /><br/>

    密码：<input type="password" name="userpwd" /><br/>

    <input type="submit" value="登录" />

    <a href="indexReg.action">去注册</a>

</form>

</body>

</html>

再新建一个register.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"

         pageEncoding="UTF-8"%>

<!DOCTYPE html>

<html>

<head>

    <meta charset="UTF-8">

    <title>Insert title here</title>

</head>

<body>

<h2>注册页面</h2>

<form action="reg.action" method="post">

    用户名：<input type="text" name="username" /><br/>

    密码：<input type="password" name="userpwd" /><br/>

    <input type="submit" value="注册" />

    <a href="index.action">去登录</a>

</form>

</body>

</html>

还有一个登陆成功后跳转的主页 success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"

         pageEncoding="UTF-8"%>

<!DOCTYPE html>

<html>

<head>

    <meta charset="UTF-8">

    <title>Insert title here</title>

</head>

<body>

<h2>成功！</h2>

</body>

</html>

8.测试

运行成功！截图如下：
