父模块pom

2.Dao模块

1）创建Hibernate核心配置文件（hibernate.cfg.xml；文件名不能修改）

主要设置一些配置以及读取元配置文件

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <!-- 会话工厂 -->
    <session-factory>
        <!-- 数据库方言，根据数据库选择 -->
        <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

        <!--为了方便调试是否在运行hibernate时在日志中输出sql语句 -->
        <property name="hibernate.show_sql">true</property>

        <!-- 是否对日志中输出的sql语句进行格式化 -->
        <property name="hibernate.format_sql">true</property>

        <!-- 自动建表 -->
        <property name="hibernate.hbm2ddl.auto">update</property>

        <!-- 加载映射文件 -->
        <mapping resource="com/ssh/entity/Customer.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

hibernate.cfg.xml

2）创建元配置文件（Customer.hbm.xml；命名格式不能随便取）

可以根据该配置文件自动映射为表，该配置文件对应一个实体类

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<!-- Generated 2016-2-26 16:58:40 by Hibernate Tools 4.3.1.Final -->
<hibernate-mapping>
    <class name="com.ssh.entity.Customer" table="cst_customer"  optimistic-lock="version">
        <id name="custId" type="java.lang.Long">
            <column name="cust_id" />
            <generator class="identity" />
        </id>
        <property name="custName" type="string">
            <column name="cust_name" length="32" not-null="true"></column>
        </property>
        <property name="custUserId" type="java.lang.Long">
            <column name="cust_user_id"></column>
        </property>
        <property name="custCreateId" type="java.lang.Long">
            <column name="cust_create_id"></column>
        </property>
        <property name="custIndustry" type="string">
            <column name="cust_industry" length="32"></column>
        </property>
        <property name="custLevel" type="string">
            <column name="cust_level" length="32"></column>
        </property>
        <property name="custLinkman" type="string">
            <column name="cust_linkman" length="64"></column>
        </property>
        <property name="custPhone" type="string">
            <column name="cust_phone" length="64"></column>
        </property>
        <property name="custMobile" type="string">
            <column name="cust_mobile" length="16"></column>
        </property>
    </class>
</hibernate-mapping>

customer.hbm.xml

3）创建Spring核心配置文件（applicationContext-dao.xml）

主要配置数据库的数据源（数据库连接池）；

Hibernate的工厂（创建SessionFactory工厂）；

配置事务管理；

<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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    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.xsd
    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!-- 数据库连接池 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver" />
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssh_maven" />
        <property name="user" value="root" />
        <property name="password" value="admins" />
    </bean>

    <!-- 配置sessionFactory -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <!-- 依赖dataSource -->
        <property name="dataSource" ref="dataSource" />
        <!-- 创建工厂需要加载hibernate映射文件 -->
        <property name="configLocations" value="classpath:hibernate.cfg.xml"></property>
    </bean>

    <bean id="customerDao" class="com.ssh.dao.impl.CustomerImpl">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>

</beans>

application-dao.xml

4）接口和实体类

package com.ssh.dao;

import com.ssh.entity.Customer;

public interface CustomerDao {

    /**
     * 通过id查询用户
     * @param CustomerId
     * @return
     */
    public Customer findCustomerById(Long CustomerId);
}

CustomerDao

package com.ssh.dao.impl;

import com.ssh.dao.CustomerDao;
import com.ssh.entity.Customer;
import org.springframework.orm.hibernate5.support.HibernateDaoSupport;

public class CustomerImpl extends HibernateDaoSupport implements CustomerDao {

    @Override
    public Customer findCustomerById(Long CustomerId) {
        return this.getHibernateTemplate().get(Customer.class, CustomerId);
    }

}

CustomerImpl

package com.ssh.entity;

public class Customer {
    private Long custId;
    private String custName;
    private Long custUserId;
    private Long custCreateId;
    private String custIndustry;
    private String custLevel;
    private String custLinkman;
    private String custPhone;
    private String custMobile;

    public Long getCustId() {
        return custId;
    }
    public void setCustId(Long custId) {
        this.custId = custId;
    }
    public String getCustName() {
        return custName;
    }
    public void setCustName(String custName) {
        this.custName = custName;
    }
    public Long getCustUserId() {
        return custUserId;
    }
    public void setCustUserId(Long custUserId) {
        this.custUserId = custUserId;
    }
    public Long getCustCreateId() {
        return custCreateId;
    }
    public void setCustCreateId(Long custCreateId) {
        this.custCreateId = custCreateId;
    }
    public String getCustIndustry() {
        return custIndustry;
    }
    public void setCustIndustry(String custIndustry) {
        this.custIndustry = custIndustry;
    }
    public String getCustLevel() {
        return custLevel;
    }
    public void setCustLevel(String custLevel) {
        this.custLevel = custLevel;
    }
    public String getCustLinkman() {
        return custLinkman;
    }
    public void setCustLinkman(String custLinkman) {
        this.custLinkman = custLinkman;
    }
    public String getCustPhone() {
        return custPhone;
    }
    public void setCustPhone(String custPhone) {
        this.custPhone = custPhone;
    }
    public String getCustMobile() {
        return custMobile;
    }
    public void setCustMobile(String custMobile) {
        this.custMobile = custMobile;
    }

}

Customer

struts.xml

4）Action

package com.ssh.action;

import com.opensymphony.xwork2.ActionSupport;
import com.ssh.entity.Customer;
import com.ssh.service.CustomerService;

public class CustomerAction extends ActionSupport {

    //注入service
    private CustomerService customerService;

    //属性封装到custId
    private Long custId;//客户id

    //存放到值栈（get方式）
    private Customer customer;//客户信息

    public CustomerService getCustomerService() {
        return customerService;
    }
    public void setCustomerService(CustomerService customerService) {
        this.customerService = customerService;
    }
    public Long getCustId() {
        return custId;
    }
    public void setCustId(Long custId) {
        this.custId = custId;
    }
    public Customer getCustomer() {
        return customer;
    }
    public void setCustomer(Customer customer) {
        this.customer = customer;
    }

    //action方法
    public String queryCustomer(){
        customer=customerService.findCustomerById(custId);
        return "success";
    }

}

CustomerAction

5.Web.xml中的配置

配置监听器读取applicationContext-*.xml

配置Struts2的核心拦截器（过滤器）

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    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">

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
<!--         <param-value>classpath:applicationContext.xml</param-value> -->
        <param-value>classpath*:applicationContext-*.xml</param-value>
    </context-param>

    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <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>

</web-app>

web.xml

6.其他一些配置

1）返回的页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
访问网址：http://localhost:8080/ssh/customerAction_queryCustomer.action?custId=1
这是一个信息页面
${customer.custName }
</body>
</html>

info.jsp

2）数据库连接池

#加jdbc前缀的目的是为了避免后面的名字与其他地方名字冲突
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssh_maven?characterEncoding=utf-8
jdbc.username=root
jdbc.password=admins

3）日志

#日志文件
log4j.rootLogger=DEBUG,stdout
log4j.logger.org.mybatis=DEBUG
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p %d %C: %m%n

至此SSH分模块整合完毕
