利用Intellij+MAVEN搭建Spring+Mybatis+MySql+SpringMVC项目详解

这两天在公司实习，师父让我先熟悉Intellij软件的使用和SpringMVC框架。话不多说，先利用这些搭建一个小环境吧。

1 创建MAVEN项目：File-NEW-MAVEN-create from..前打勾--选下面的org.apache..archetypes:maven-archetype-webapp,点击next

后面的项目名称：

GroupId:项目的名称，
ArtiFactId:项目的模块名称（建议用项目名称-模块名称来表示），
Version:项目版本的名称
如：groupID：SpringMVC；ArtiFactId：SpringMVC-Demo，version:默认完成后，IDEA就自动给我们构建了一个空的maven项目.

2  配置pom.xml文件，这里利用<dependency></dependency>标签导入需要的库。这里需要导入的有junit , spring , springmvc , mysql , mybatis , jstl等等，详见下面的配置文件：

  1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3 src下面新建java包，将其设置为source root(在java包上点击右键，选择Mark Directory As Source Root),依次建如图类结构：

利用Intellij+MAVEN搭建Spring+Mybatis+MySql+SpringMVC项目详解

1）创建接口EmployeeMapper.java,这里是采用Mybatis的注解的方式，要在后面的spring-mybatis文件中去注册接口

  1. package com.mybatis.dao;
  2. import com.mybatis.model.Employee;
  3. import org.apache.ibatis.annotations.Select;
  4. import java.util.List;
  5. /**
  6. * Created by wanggenshen_sx on 2016/12/26.
  7. */
  8. public interface EmployeeMapper {
  9. @Select("select id,lastName,email from employee where id=#{id}")
  10. Employee getEmployeeById(int id);
  11. @Select("select * from employee")
  12. List<Employee> getAllEmployees();
  13. }
package com.mybatis.dao;

import com.mybatis.model.Employee;

import org.apache.ibatis.annotations.Select;

import java.util.List;

/**

 * Created by wanggenshen_sx on 2016/12/26.

 */

public interface EmployeeMapper {

	@Select("select id,lastName,email from employee where id=#{id}")

	Employee getEmployeeById(int id);

	@Select("select * from employee")

	List<Employee> getAllEmployees();

}

2）实体类：Employee.java

  1. package com.mybatis.model;
  2. /**
  3. * Created by wanggenshen_sx on 2016/12/23.
  4. */
  5. public class Employee {
  6. private int id;
  7. private String lastName;
  8. private String email;
  9. public int getId() {
  10. return id;
  11. }
  12. public void setId(int id) {
  13. this.id = id;
  14. }
  15. public String getLastName() {
  16. return lastName;
  17. }
  18. public void setLastName(String lastName) {
  19. this.lastName = lastName;
  20. }
  21. public String getEmail() {
  22. return email;
  23. }
  24. public void setEmail(String email) {
  25. this.email = email;
  26. }
  27. @Override
  28. public String toString() {
  29. return "Employee [id=" + id + ", lastName=" + lastName + ", email="
  30. + email+" ]" ;
  31. }
  32. public Employee(){}
  33. }
package com.mybatis.model;

/**

 * Created by wanggenshen_sx on 2016/12/23.

 */

public class Employee {

	private int id;

	private String lastName;

	private String email;

	public int getId() {

		return id;

	}

	public void setId(int id) {

		this.id = id;

	}

	public String getLastName() {

		return lastName;

	}

	public void setLastName(String lastName) {

		this.lastName = lastName;

	}

	public String getEmail() {

		return email;

	}

	public void setEmail(String email) {

		this.email = email;

	}

	@Override

	public String toString() {

		return "Employee [id=" + id + ", lastName=" + lastName + ", email="

				+ email+" ]" ;

	}

	public Employee(){}

}

3) Service层：

创建EmployeeService接口

  1. package com.mybatis.service;
  2. import com.mybatis.model.Employee;
  3. import java.util.List;
  4. /**
  5. * Created by wanggenshen_sx on 2016/12/26.
  6. */
  7. public interface EmployeeService {
  8. Employee getEmployee(int id);
  9. List<Employee> getEmployees();
  10. }
package com.mybatis.service;

import com.mybatis.model.Employee;

import java.util.List;

/**

 * Created by wanggenshen_sx on 2016/12/26.

 */

public interface EmployeeService {

	Employee getEmployee(int id);

	List<Employee> getEmployees();

}

创建EmployeeServiceImpl实现类：注意添加@Service注解

package com.mybatis.service;

import com.mybatis.dao.EmployeeMapper;

import com.mybatis.model.Employee;

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

import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Created by wanggenshen_sx on 2016/12/26.
 */
@Service

public class EmployeeServiceImpl implements EmployeeService {

   public EmployeeServiceImpl() {

      System.out.printf("init EmployeeServiceImpl");

   }

   @Autowired

   private EmployeeMapper employeeMapper;

   @Override

   public Employee getEmployee(int id){

      return employeeMapper.getEmployeeById(id);

   }

   public List<Employee> getEmployees(){

      return employeeMapper.getAllEmployees();

   }

}

4）在spring配置文件中整合mybatis:spring-mybatis.xml

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

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

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

    <!--自动扫描含有@Service的类，将其注入为bean -->

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

    <context:component-scan base-package="com.mybatis.dao" />

    <!-- 1. 数据源 : DriverManagerDataSource -->

    <bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>

        <property name="url" value="jdbc:mysql://localhost:3306/mytest"/>

        <property name="username" value="root"/>

        <property name="password" value="920614"/>

    </bean>

    <!--

        2. mybatis的SqlSession的工厂: SqlSessionFactoryBean

            dataSource / typeAliasesPackage

    -->

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

        <property name="dataSource" ref="datasource"/>

        <property name="typeAliasesPackage" value="com.mybatis.model"/>

    </bean>

    <!--

        3. mybatis自动扫描加载Sql映射文件 : MapperScannerConfigurer

            sqlSessionFactory / basePackage

    -->

    <bean id="config" class="org.mybatis.spring.mapper.MapperScannerConfigurer">

       <property name="basePackage" value="com.mybatis.dao"/>

        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />

    </bean>

    <!-- 4. 事务管理 : DataSourceTransactionManager -->

    <bean id="manager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

        <property name="dataSource" ref="datasource"/>

    </bean>

    <!-- 5. 使用声明式事务 -->

    <tx:annotation-driven transaction-manager="manager" />

</beans>

建测试类：EmployeeTest.java

package com.mybatis.test;

import com.mybatis.model.Employee;

import com.mybatis.service.EmployeeService;

import org.junit.Test;

import org.junit.runner.RunWith;

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

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import java.util.List;

/**
 * Created by wanggenshen_sx on 2016/12/27.
 */
@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = { "classpath:spring-mybatis.xml" })

public class EmployeeTest {

   @Autowired

   private EmployeeService employeeService;

   @Test

   public void testGetEmployeeById(){

      Employee employee = employeeService.getEmployee(1);

      System.out.print(employee);

   }

   @Test

   public void testGetAll(){

      List<Employee> employees=employeeService.getEmployees();

      System.out.print(employees);

   }

}

能输出并显示数据库表的内容，即表示Spring整合Mybatis成功，接下来加入SpringMVC内容，将读取的内容显示在页面上。

4 创建springmvc-servlet.xml,配置视图信息。

<?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:context="http://www.springframework.org/schema/context"

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

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

      http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd

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

    <!--注解-->

    <mvc:annotation-driven/>

    <!--处理静态资源-->

    <mvc:default-servlet-handler/>

    <!-- 自动扫描controller包下的有@Controller注解的，注入为bean -->

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

    <!--配置视图解析器-->

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

        <property name="prefix" value="/WEB-INF/views/"/>

        <property name="suffix" value=".jsp"/>

        <property name="viewClass"  value="org.springframework.web.servlet.view.JstlView" />

    </bean>

</beans>

5 建控制类：
EmployeeController.java

package com.mybatis.controller;

import com.mybatis.model.Employee;

import com.mybatis.service.EmployeeService;

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

import org.springframework.stereotype.Controller;

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

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

import java.util.List;

import java.util.Map;

/**
 * Created by wanggenshen_sx on 2016/12/26.
 */
@Controller

public class EmployeeController {

   @Autowired

   private EmployeeService employeeService;

   @RequestMapping(value=",Object> map){

      List<Employee> employees = employeeService.getEmployees();

       /*测试用

      if(employees==null)

         System.out.println("null");

      else

         System.out.println(employees);*/

      map.put("employees",employees);

      return "list";

   }

}

6 建立显示页面: Web-app的WEB-INF下建views包下建list.jsp：

注意此处一定要加上

page false

否则无法使用jstl标签。

taglib chttp://java.sun.com/jsp/jstl/core" %>

<%--

<body>

                <table border="1" cellspacing="0" cellpadding="10">

                    <tr>

                        <th>ID</th>

                        <th>LastName</th>

                        <th>Email</th>

                    </tr>

                    c="}="emp">

                        <tr>

                            <th>}</th>

                            <th>}</th>

                            <th>}</th>

                        </tr>
c:forEach>

                </table>

</body>

</html>

7 配置web.xml ,分别指定spring,springmvc配置文件的位置。注意这里一定要有四个部分，即<context-param>,<servlet>,<servlet-mapping>,<listener>.

我在这里没有添加<listener>标签，spring无法初始化，出现了【Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'employeeController': Unsatisfied dependency expressed through field 'employeeService': No qualifying bean of type [com.mybatis.service.EmployeeService] found for dependency [com.mybatis.service.EmployeeService]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: 】错误。
