**一、jar包**  
  
首先引入Struts和json所需的jar包。

**二、前台代码**

**三、Action**

import java.util.HashMap;
    import java.util.Map;
    import net.sf.json.JSONObject;
    
    public class RegisterAction {
    
    	private String name;
    	private String sex;
    	private String age;
    
    	private String result;
    
    	public String register() {
    
    		Map<String, Object> map = new HashMap<String, Object>();
    		map.put("msg", true);
    		map.put("name", name);
    		map.put("sex", sex==null?"":("1".equals(sex)?"男":"女"));
    		map.put("age", age);
    		JSONObject json = JSONObject.fromObject(map);//将map对象转换成json类型数据
    		result = json.toString();// 将result传给页面
    		
    		return "success";
    	}
    
    	public String getName() {
    		return name;
    	}
    
    	public void setName(String name) {
    		this.name = name;
    	}
    
    	public String getSex() {
    		return sex;
    	}
    
    	public void setSex(String sex) {
    		this.sex = sex;
    	}
    
    	public String getAge() {
    		return age;
    	}
    
    	public void setAge(String age) {
    		this.age = age;
    	}
    
    	public String getResult() {
    		return result;
    	}
    
    	public void setResult(String result) {
    		this.result = result;
    	}
    
    }

**四、Struts配置**

<struts>
    	<package name="build" extends="json-default">
    		<action name="RegisterAction" method="register" class="com.home.RegisterAction">
     			 <result type="json">
                    <param name="root">result</param> 
                </result>
    		</action>
    	</package>
    </struts>
