Example of using automatic assembly operation for the integration of spring and struts
•
Java
This paper describes the integration of spring and struts using automatic assembly operations. Share with you for your reference, as follows:
I. web configuration
<?xml version="1.0" encoding="GBK"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">
<!-- 使用ContextLoaderListener初始化spring容器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<!-- 定义Struts 2的FilterDispathcer的Filter -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<!-- FilterDispatcher用来初始化Struts 2并且处理所有的WEB请求。 -->
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
II. ApplicationContext XML configuration
<?xml version="1.0" encoding="GBK"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">
<!-- 定义一个业务逻辑组件，实现类为MyServiceImp，
此处的id必须与Action的setter方法名对应 -->
<bean id="ms"
class="org.crazyit.app.service.impl.MyServiceImpl"/>
</beans>

IV. struts configuration
<?xml version="1.0" encoding="GBK"?>
<!-- 指定Struts 2配置文件的DTD信息 -->
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<!-- 配置了系列常量 -->
<constant name="struts.i18n.encoding" value="GBK"/>
<constant name="struts.devMode" value="true"/>
<constant name="struts.enable.DynamicMethodInvocation" value="false"/>
<package name="lee" extends="struts-default">
<!-- 定义处理用户请求的Action -->
<action name="login"
class="org.crazyit.app.action.LoginAction">
<!-- 为两个逻辑视图配置视图页面 -->
<result name="error">/WEB-INF/content/error.jsp</result>
<result>/WEB-INF/content/welcome.jsp</result>
</action>
<!-- 让用户直接访问该应用时列出所有视图页面 -->
<action name="*">
<result>/WEB-INF/content/{1}.jsp</result>
</action>
</package>
</struts>
Five actions
package org.crazyit.app.action;
import com.opensymphony.xwork2.ActionSupport;
import org.crazyit.app.service.*;
public class LoginAction extends ActionSupport
{
// 下面是用于封装用户请求参数的两个成员变量
private String username;
private String password;
// 系统所用的业务逻辑组件
private MyService ms;
// 设值注入业务逻辑组件所必需的setter方法
public void setMs(MyService ms)
{
this.ms = ms;
}
// username的setter和getter方法
public void setUsername(String username)
{
this.username = username;
}
public String getUsername()
{
return this.username;
}
// password的setter和getter方法
public void setPassword(String password)
{
this.password = password;
}
public String getpassword()
{
return this.password;
}
// 处理用户请求的execute方法
public String execute() throws Exception
{
// 调用业务逻辑组件的validLogin()方法
// 验证用户输入的用户名和密码是否正确
if (ms.validLogin(getUsername(),getpassword()) > 0)
{
addActionMessage("哈哈，整合成功！");
return SUCCESS;
}
return ERROR;
}
}
Vi. service
1 interface
package org.crazyit.app.service;
public interface MyService
{
int validLogin(String username,String pass);
}
2 implementation class
package org.crazyit.app.service.impl;
import org.crazyit.app.service.*;
public class MyServiceImpl implements MyService
{
public int validLogin(String username,String pass)
{
// 此处只是简单示范，故直接判断用户名、密码是否符合要求
if ( username.equals("crazyit.org")
&& pass.equals("leegang") )
{
return 99;
}
return -1;
}
}
