struts2.1.6利用convention-plugin和json-plugin实现json零配置
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
<filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
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
<struts>
<!-- 结果资源所在路径 -->
<constant name="struts.convention.result.path" value="/"/>
</struts>
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
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="js/jquery.js"></script>
<title>Insert title here</title>
<script type="text/javascript">
function alt() {
$.getJSON("json/json-test.action", function(json){alert(json.name);});
};
function altTest() {
$.getJSON("json/json-test!test.action", function(json){alert(json.name);});
};
</script>
</head>
<body>
<button id="a" onclick="alt();">点我-Default</button>
<button id="b" onclick="altTest();">点我-Test</button>
</body>
</html>
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!!”
