三大框架整合模板ssh

1.web.xml配置

org.springframework.web.context.ContextLoaderListener contextConfigLocation classpath:applicationContext.xml openSessionInView org.springframework.orm.hibernate5.support.OpenSessionInViewFilter struts2 org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter openSessionInView /* struts2 /*

2.db.properties配置

jdbc.jdbcUrl=jdbc:mysql:///数据库名称?characterEncoding=UTF-8
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=用户名
jdbc.password=密码

3.struts.xml配置

<?xml version="1.0" encoding="UTF-8"?>

<!-- #  struts.objectFactory = spring   将action的创建交给spring容器    
        struts.objectFactory.spring.autoWire = name spring负责装配Action依赖属性
        -->
<constant name="struts.objectFactory" value="spring"></constant>

<!-- 配置拦截器栈 -->
        <interceptor-stack name="myStack">
            <interceptor-ref name="privilegeInterceptor">
                <param name="excludeMethods">login,register</param>
            </interceptor-ref>
            <interceptor-ref name="defaultStack"></interceptor-ref>
        </interceptor-stack>
    </interceptors>
<!-- 指定默认拦截器栈 -->
<default-interceptor-ref name="myStack"></default-interceptor-ref>

<global-results>
    <result name="toLogin" type="redirect" >/login.jsp</result>
</global-results>


<global-exception-mappings>
    <exception-mapping result="error" exception="java.lang.RuntimeException"></exception-mapping>
</global-exception-mappings>


<action name="action类的名字_*" class="spring注解的名称" method="{1}" >
    
</action>

4.applicationContext.xml的配置

<?xml version="1.0" encoding="UTF-8"?>

<context:property-placeholder location=“classpath:db.properties” />

<context:component-scan base-package=“cn.hr”></context:component-scan>

org.hibernate.dialect.MySQLDialect true true update

5.dao层的基本配置和书写

@Repository(“dao层的属性注入名称”)
public class 实现类名 extends HibernateDaoSupport implements 接口名{
//固定格式
@Resource(name=“sessionFactory”)
public void setSF(SessionFactory sf) {
super.setSessionFactory(sf);
}

}

6.service层基本配置和书写

@Service(“service层的属性注入名称”)
//下面的属性是设置是否只读，对于不只读的方法将true改为false
@Transactional(isolation=Isolation.REPEATABLE_READ,propagation=Propagation.REQUIRED,readOnly=true)
public class 实现类名 implements 接口名{
@Resource(name=“dao层的属性注入名称”)
private StartPageDao spd;
}

7.action层基本配置和书写

@Scope(“prototype”)
//设置多例
@Controller(“action层的属性注入名称”)
public class 实现类名 extends ActionSupport{
@Resource(name=“service层的属性注入名称”)
private StartPageService startpageservice;
//提供了一个供给发送前端ajax的方法
public String index() throws Exception{

// 1.访问service层的方法
List sp = (List) startpageservice.findStartImage();
// 2.将数据放回给前端
Gson gson = new Gson();
String json = gson.toJson(sp);
ServletActionContext.getResponse().setContentType(“application/json;charset=utf-8”);
ServletActionContext.getResponse().getWriter().write(json);
return null;
}
}
