            </plugin>

        </plugins>

    </build>

</project>

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 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>

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
