1、 SSH Web工程属性

spring beans springMVC配置：
spring-mvc.xml springMVC配置.xml文档

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

spring-common.xml 数据源、会话工厂、事务、事务代理等配置

<?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">

    <!-- 数据源，mysql数据库连接参数配置-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url" value="jdbc:mysql://localhost:3306/your-db"></property>
        <property name="username" value="your-username"></property>
        <property name="password" value="your-password"></property>
    </bean>

    <!-- 配置SessionFactory， 注解类：完成orm功能 -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
            </props>

            </list>
        </property>
    </bean>

    <!-- 配置一个事务管理器 -->
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

    <!-- 配置事务，使用代理的方式 -->

                <prop key="*">PROPAGATION_REQUIRED</prop>
            </props>
        </property>
    </bean>
</beans>

注解类：User.java
—- 通过上面的.xml配置，最终会访问mysql中的相关数据库中的user表

package com.ssh.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import org.hibernate.annotations.GenericGenerator;
@Entity
@Table(name="user")
public class User {
    @Id
    @GeneratedValue(generator="system-uuid")
    @GenericGenerator(name = "system-uuid",strategy="uuid")
    @Column(length=32)
    private String id;

    @Column(length=32)
    private String userName;

    @Column(length=32)
    private String age;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }

}

spring-beans.xml 每一个Bean对应Spring容器里的一个Java实例, 配置spring中各实例

<?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">

<!-- spring-common.xml中的会话工厂实例，作为属性传入 UserDaoImpl-->
    <bean id="userDao" class="com.ssh.dao.UserDaoImpl">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>

    <bean id="userManagerBase" class="com.ssh.service.UserManagerImpl">
        <property name="userDao" ref="userDao"></property>
    </bean>

    <!-- 此处为代理 -->
    <bean name="userManager" parent="transactionProxy">
        <property name="target" ref="userManagerBase"></property>
    </bean>
</beans>

web.xml web总配置文件，其中加载spring-*.xml、配置spring 、springMVC等

<?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">
  <display-name>json_test</display-name>
  <welcome-file-list>
    <welcome-file>login.jsp</welcome-file>
  </welcome-file-list>

  <!-- 加载所有的配置文件 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:**/spring-*.xml</param-value>
  </context-param>

  <!-- 配置Spring监听 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- 配置SpringMVC -->
  <servlet>
    <servlet-name>springMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/**/spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springMVC</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!-- 配置字符集 -->
  <filter>
    <filter-name>encodingFilter</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>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- 配置Session -->
  <filter>
    <filter-name>openSession</filter-name>
    <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>openSession</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

2、部署web项目到tomcat，启动服务

3、Web Brower 运行界面

运行时对应的mysql 界面：
