@Autowired与JUnit测试 [英] @Autowired with JUnit tests

问题描述

我已经使用了JUnit，但是某些测试存在一些问题，这些测试在Spring bean中具有@Autowired批注，而当我引用它们时，@ Autowired的bean始终为NULL.

I´ve using JUnit but some tests have some issues, these tests have @Autowired annotation inside the Spring beans and when i reference them the beans that are @Autowired were always NULL.

这是示例代码:

     public class Test {

                 protected ApplicationContext ac;

                 @Before
                 public void setUp() {
                     ac = new FileSystemXmlApplicationContext("classpath:config/applicationContext.xml"
                     "classpath:config/test-datasources.xml");
                 }

                 @Test
                 public void testRun() throws Exception {
                        IManager manager =  (IManager)this.ac.getBean("manager");
                        manager.doSomething();
                 }
    }

    @Service
    public class Manager implements IManager {

            public boolean doSomething() throws Exception {
                 ParametersJCSCache parametersJCSCache = new ParametersJCSCache();
                 String paramValue = parametersJCSCache.getParameter("XPTO");
                 ...
            }
    }

    public class ParametersJCSCache extends SpringBeanAutowiringSupport {

          @Autowired
          private IParameterManager parameterManager;  //THIS IS NULL
    }

当调用Manager对象时，Spring会生成代理，但是当访问@Autowired parameterManager时，该对象为null，因此，我无法测试此方法.

When invoking the Manager object the Spring generates the proxy but when accessing the @Autowired parameterManager the object is null, and with this issue i can´t test this method.

有人知道是什么原因造成的吗?为什么没有注入物体?它可以在Web应用程序的上下文中很好地工作，但是在测试上下文中始终为NULL.

Any idea what is causing this? Why does the object not get injected? It works well in the context of a web application, but in the test context is always NULL.

推荐答案

我终于找到了解决我问题的方法. 查找此帖子 SpringBeanAutowiringSupport不会在jUnit测试中注入bean ，做这样的事情，JUnit测试就可以了.

I've finally found a solution to my problem. Find this post SpringBeanAutowiringSupport does not inject beans in jUnit tests and do something like this the JUnit tests works.
