一、导入所需包，包括Struts2所需的各jar包，再导入struts2-convention-plugin-2.1.jar和jsonplugin-0.34.jar
二、在Web.xml添加Struts2
web.xml
struts2 org.apache.struts2.dispatcher.FilterDispatcher struts2 /*
三、修改struts.xml，配置struts2-convention-plugin。并修改convention-plugin默认的结果资源路径为webroot/
struts.xml
四、编写Action代码
com.fish.action.json.JsonTestAction
package com.fish.action.json;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import com.opensymphony.xwork2.ActionSupport;
@ParentPackage("json-default")
@Result(type="json",name="test")
public class JsonTestAction extends ActionSupport {
private static final long serialVersionUID = 4242612202520616657L;
private String name = "fish119";
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Action(value="test",results={@Result(type="json",name="test")})
public String test() throws Exception{
this.name += ": Test method!!";
return "test";
}
@Action(results={@Result(type="json",name="success")})
public String execute() throws Exception{
this.name +=": This is the default method!";
return SUCCESS;
}
}
五、编写页面文件
index.html
Insert title here
六、测试
在地址栏输入 http://localhost:8080/ConventionTest/index.html
点击“点我-Default”按钮，调用action中的execute方法，弹出“This is the default method!”
点击“点我-Test”按钮，调用action中的test方法，弹出“Test method!!”
