SSH整合

1.先创建一个maven项目

2.在pom.xml里引入以下相关jar包：

struts2-core  ,  struts2-json-plugin  ,  struts2-spring-plugin;

log4j-api  ,  log4j-core  

spring-context  , spring-orm  ,   HikariCP(数据源的包);

hibernate-core

3.在web.xml里输入相关过滤器

<!-- spring -->
<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>

 <!-- struts2 -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

4.创建一个applicationContext.xml配置如下：

<?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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">
        
    <!-- 启动bean的扫描 -->
    <context:component-scan base-package="com.blb"></context:component-scan>
    
    <bean class="com.blb.test.Test" id="test"></bean>
    
    <!-- 连接池 -->
    <bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource"
        destroy-method="shutdown">
        <property name="jdbcUrl"
            value="jdbc:mysql://localhost:3306/hibernate?useUnicode=true&amp;characterEncoding=UTF-8" />
        <property name="username" value="root" />
        <property name="password" value="root" />
        <property name="readOnly" value="false" />
        <property name="connectionTimeout" value="30000" />
        <property name="idleTimeout" value="600000" />
        <property name="maxLifetime" value="1800000" />
        <property name="maximumPoolSize" value="15" />
    </bean>

    
    <bean id="mySessionFactory"
        class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocations" value="classpath:hibernate.cfg.xml"></property>
    </bean>
</beans>

5.创建一个struts.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
    "http://struts.apache.org/dtds/struts-2.5.dtd">

<struts>
    <!-- 开发者模式 -->
    <constant name="struts.devMode" value="true" />
    <constant name="struts.enable.DynamicMethodInvocation" value="true"/>

    <package name="basicstruts2" extends="struts-default,json-default" strict-method-invocation="false">
    
        <action name="aaa" class="test">
            <result name="success">/login.jsp</result>
        </action>
    </package>

</struts>

6.创建一个hibernate.cfg.xml配置如下：

<?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>
    <session-factory>
        <!-- 方言 -->
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

        <!-- 配置映射文件 -->
        <mapping class="com.blb.entity.user" />
    </session-factory>
</hibernate-configuration>     

7.创建一个log4j2.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <Appenders>
        <Console name="STDOUT" target="SYSTEM_OUT">
            <PatternLayout pattern="%d %-5p [%t] %C{2} (%F:%L) - %m%n"/>
        </Console>
    </Appenders>
    <Loggers>
        <Logger name="com.opensymphony.xwork2" level="info"/>
        <Logger name="org.apache.struts2" level="debug"/>
        <Root level="warn">
            <AppenderRef ref="STDOUT"/>
        </Root>
    </Loggers>
</Configuration>

8.创建一个User实体类：

package com.blb.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="s_student")
public class user {

    @Id
    private String sid;
    @Column(name = "name")
    private String usermane;
    
    public String getSid() {
        return sid;
    }

    public void setSid(String sid) {
        this.sid = sid;
    }

    public String getUsermane() {
        return usermane;
    }

    public void setUsermane(String usermane) {
        this.usermane = usermane;
    }

    @Override
    public String toString() {
        return "user [sid=" + sid + ", usermane=" + usermane +  "]";
    }
    
}

9.最后就可以写测试类开始测试了。
