json-struts使用教程（1）-初识json-struts

json-struts是一个实现了任意java对象自动转换JSON 参数自动匹配和赋值的j2ee框架。其项目源码放在svn://www.svn999.com/opopop880.json_struts,用户名anyoneuser
密码anyoneuser ；主要是运用于移动开发后台。提交的前端提交的请求不区分GET还是POST，框架能够完成自动赋值给Java
Bean参数，支持属性模型和域模型；能够与Spring集成；支持自定义访问URL；所有的结果统一转换到JSON返回，支持自定义转换格式。

json-struts必须依赖项目reflectASM和fastJSON。

新建J2EE WEB工程web 下载jar包拷贝到WEB_INF下Lib文件夹，修改web.xml文件

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

</welcome-file-list>

</web-app>

核心过滤器DispatcherFilter中间增加了频繁请求过滤请求，能够阻止用户频繁刷新页面或者使用压力测试工具攻击！新建java类User

package test;

public class User {
public String name;

private int age;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getAge() {
return age;
}

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

}

新建访问类Index

package test;

import org.jsonstruts.annotation.WebUrl;

@WebUrl("/index")
public class Index{

private String name;

private int age;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}
public Object execute() {

User user = new User();
user.setName(name);
user.setAge(age);
return user;
}

}

然后启动项目，查看启动日志，查看访问URL映射
