Struts2 + Spring3 + JUnit4 集成

Question

我尝试为 Struts2 和 Spring3 集成编写单元测试。 我使用 struts2-junit 插件进行 jUnit4 测试。 但问题是动作代理返回 null。

我该如何解决？

下面的代码是我的测试类和其他配置。 测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:applicationContext.xml" })
public class StrutsTest extends StrutsSpringJUnit4TestCase<MyAction> {
    @Test
    public void myTest() throws Exception {
        ActionProxy proxy = getActionProxy("/myaction");
        MyAction myAction = (MyAction) proxy.getAction();
        request.setParameter("personBean.firstName", "Joe");
        request.setParameter("personBean.lastName", "Doe");
        String result = myAction.execute();
        assertEquals("Error", ActionSupport.SUCCESS, result);
    }
}

MyAction.java：

@Component
@Scope("prototype")
public class MyAction implements Action  {
    private Person personBean;

    public String execute() throws Exception {
        System.out.println("MyAction is called!");
        System.out.println("personBean.firstName"+personBean.getFirstName());
        System.out.println("personBean.firstName"+personBean.getFirstName());
        return ActionSupport.ERROR;
    }

}

1. 确保您已包含 struts2-spring-plugin：

   <dependency>
       <groupId>org.apache.struts</groupId>
       <artifactId>struts2-spring-plugin</artifactId>
       <version>STRUTS_VERSION</version>
   </dependency>
   

2. 在 web.xml 中尝试使用

   <param-value>classpath*:applicationContext.xml</param-value>
   

3. 在struts.xml中尝试使用

   <constant name="struts.objectFactory" 
             value="org.apache.struts2.spring.StrutsSpringObjectFactory" />
   

第一次尝试在我脑海中闪过……希望对你有所帮助。
