Struts2.3.12 junit4 testcase请求和会话为空

我已经完成了这个解决方案： Struts 2 JUnit Plugin v2.2.3：Test Class Extending StrutsTestCase; ‘request’为空

但是我已经没有struts2-spring插件了，我也没有在我的应用程序中使用spring。

我有3个测试用例，2个请求失败，为null，一个失败，会话为null

第一个Stacktrace

java.lang.NullPointerException at org.apache.struts2.interceptor.MessageStoreInterceptor.before(MessageStoreInterceptor.java:228) at org.apache.struts2.interceptor.MessageStoreInterceptor.intercept(MessageStoreInterceptor.java:193) at com.opensymphony.xwork2.DefaultActionInvocation.invoke(DefaultActionInvocation.java:246) at org.apache.struts2.impl.StrutsActionProxy.execute(StrutsActionProxy.java:54) at actions.TestIoOptimizationAction.login(TestIoOptimizationAction.java:29) 

对应于

  Collection actionErrors = (Collection) session.get(actionErrorsSessionKey); 

第二和第三测试堆栈跟踪

 java.lang.NullPointerException at org.apache.struts2.impl.StrutsActionProxy.getErrorMessage(StrutsActionProxy.java:69) at com.opensymphony.xwork2.DefaultActionProxy.prepare(DefaultActionProxy.java:185) at org.apache.struts2.impl.StrutsActionProxy.prepare(StrutsActionProxy.java:63) at org.apache.struts2.impl.StrutsActionProxyFactory.createActionProxy(StrutsActionProxyFactory.java:39) at com.opensymphony.xwork2.DefaultActionProxyFactory.createActionProxy(DefaultActionProxyFactory.java:58) at org.apache.struts2.StrutsJUnit4TestCase.getActionProxy(StrutsJUnit4TestCase.java:149) 

对应于

  String contextPath = ServletActionContext.getRequest().getContextPath(); 

我相信存在一些依赖性问题。 我尝试逐个删除一些依赖项并组合使用，但都没有工作。

这是我的POM的样子：

   javax.servlet jsp-api 2.0 test   com.paypal.sdk rest-api-sdk 0.7.1   net.sourceforge.htmlunit htmlunit 2.12 compile   org.apache.commons commons-lang3 3.0 jar compile   commons-beanutils commons-beanutils-core 1.8.3   javax.mail mail 1.4.5   commons-lang commons-lang 2.4   javax.persistence persistence-api 1.0 jar compile   mysql mysql-connector-java 5.1.6   org.hibernate hibernate-entitymanager ${hibernate.version}   org.hibernate hibernate-validator 4.0.0.GA   org.hibernate hibernate-c3p0 ${hibernate.version}   org.slf4j slf4j-log4j12 1.6.1   org.apache.tiles tiles-servlet 2.1.4   org.apache.tiles tiles-jsp 2.1.4   org.apache.struts struts2-core ${struts.version}   org.apache.struts struts2-json-plugin ${struts.version}   org.apache.struts struts2-tiles-plugin ${struts.version}   org.apache.struts struts2-junit-plugin ${struts.version}   joda-time joda-time 2.1   org.quartz-scheduler quartz 1.7.3  <!--  junit junit 4.11 test -->  commons-collections commons-collections 3.2.1 jar   org.jboss.spec jboss-javaee-6.0 1.0.0.Final pom provided   org.apache.myfaces.core myfaces-api 2.1.11   net.sf.jasperreports jasperreports 3.7.5   com.google.code.gson gson 2.2.4   xml-apis xml-apis 1.4.01    2.3.12 3.6.10.Final 3.5.1 all Tomcat  

更新 – 测试看起来像

 @Test public void login() throws Exception { request.setParameter("email", "[e-mail]"); request.setParameter("password", "22"); ActionProxy proxy = getActionProxy("login"); String result = proxy.execute(); assertEquals("success", result); System.out.println(response.getContentAsString()); } @Test public void testView() throws Exception { ActionProxy proxy = getActionProxy("/optimize/view"); String result = proxy.execute(); assertEquals("success", result); System.out.println(response.getContentAsString()); proxy = getActionProxy("/optimize/view/23"); result = proxy.execute(); assertEquals("success", result); System.out.println(response.getContentAsString()); proxy = getActionProxy("/optimize/view/110"); result = proxy.execute(); assertEquals("success", result); System.out.println(response.getContentAsString()); } @Test public void testSave() throws Exception { request.setContent("{\"id\":\"1\",\"name\":\"nitin\"}".getBytes()); request.addHeader("Content-Type", "application/json"); request.setMethod("POST"); ActionProxy proxy = getActionProxy("/save"); actions.IoOptimizationAction myAct = (actions.IoOptimizationAction) proxy.getAction(); String result = proxy.execute(); assertEquals("success", result); System.out.println(response.getContentAsString()); } 

更新我按照建议将测试更改为executeAction，因此，第二个测试现在看起来像

  @Test public void testView() throws Exception { System.out.println(ActionContext.getContext()); System.out.println(executeAction("optimize/view")); } 

错误堆栈跟踪是：

 You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set: 
 struts.devMode=false 
 in your WEB-INF/classes/struts.properties file. 

   


	







 
	
Answer 1
		      	
 如果使用getActionProxy方法执行操作，则需要将新会话映射设置为调用上下文。 
 ActionProxy actionProxy = getActionProxy("/action"); Map sessionMap = new HashMap(); actionProxy.getInvocation().getInvocationContext().setSession(sessionMap); actionProxy.execute(); 
 如果您不需要引用动作代理，则可以使用executeAction方法。 请注意， executeAction将返回结果的实际输出，而不是execute方法返回的结果。

 为避免request为null： 
 request = new MockHttpServletRequest(); 
 对于会议： 
 Map sessionMap = new HashMap(); actionProxy.getInvocation().getInvocationContext().setSession(sessionMap);

 在我的情况下，我需要从我的测试中调用super.setUp 。
