转至:http://maxrocray.iteye.com/blog/1142438

很久没有做web了，温习下struts2的json配置。

所需Jar包如下：注意加上javassist.jar,OGNL依赖它。



Web.xml配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>
            org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
        </filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

struts.xml配置: (extends="json-default")

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
  <package name="test" extends="json-default">
    <action name="test" class="com.aimee.json.TestJsonAction" method="check">
        <result type="json">
        <!-- 不包含flag属性 -->
        <param name="excludeProperties">
            flag
        </param>
        </result>
    </action>
  </package>

</struts>
