映射时发生冲突导致 struts.xml

Question

我在 MyBdbSearch class 中定义了 3 个方法，并且在 struts.xml 中映射如下。

struts.xml

    <?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>
    <include file="struts-default.xml"/>
    <package name="default" extends="struts-default">    

        <action name="bdbSearch" 
                class="com.bdb.MyBdbSearchAction"
                method="showSearchPage">
              <result name="okBdbSearchPage">/jsp/search.jsp</result>
        </action>

         <action name="bdbSearch" 
                class="com.bdb.MyBdbSearchAction"
                method="search">
              <result name="okBdbSearch">/jsp/search.jsp</result>
        </action>

        <action name="bdbSearch" 
                class="com.bdb.MyBdbSearchAction"
                method="getNextResults">
              <result name="okBdbSearch">/jsp/search.jsp</result>
        </action>
     </package>
</struts>

MyBdbSearchAction.java

public class MyBdbSearchAction extends ActionSupport implements ServletRequestAware{    

@Override
    public void setServletRequest(HttpServletRequest request) {
        // TODO Auto-generated method stub
        this.request = request;
    }



    public String showSearchPage(){

        //some initialization code
        return "okBdbSearchPage";
    }

public String search(){

        //some code
        return "okBdbSearch";
    }

public String getNextResults(){

    //some code
    return "okBdbSearch";
}
}

index.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<body>
    <s:url id="searchUrl" action="/bdbSearch" method="showSearchPage"></s:url>
    <s:a href="%{searchUrl}">
        <h4>search</h4>
    </s:a>
</body>
</html>

当 xml 文件中只配置了一种方法（showSearchPage）时，应用程序可以正常工作。但是如果所有3个方法都像上面那样配置，它会抛出下面的错误。

没有为操作定义结果 com.bdb.MyBdbSearchAction 和结果 okBdbSearchPage

为什么会有这种奇怪的行为？

Answer 1

您必须更改 .xml 文件如下：

<struts>
<include file="struts-default.xml"/>
<package name="default" extends="struts-default">    

    <action name="bdbSearch" class="com.bdb.MyBdbSearchAction">
          <result name="okBdbSearchPage">/jsp/search.jsp</result>
          <result name="okBdbSearch">/jsp/search.jsp</result>
          <result name="okBdbSearch">/jsp/search.jsp</result>
    </action>
 </package>
