【原创】写JUnit时既用Parameterized又用@Autowired出现无法成功自动注入的解决办法

• 今天下午写Junit程序时，在程序中既使用了Parameterized，又使用了Autowired，发现用 @Autowired并没有完成自动注入

………………………………
@RunWith(value=Parameterized.class)
public class TestRegisterEventMaker extends BaseSpringContextTestSupport {
………………………………………………

@Autowired
private SponsorDaoImpl sponsorDao;
private long sponsorId;
private String name;
private int type;
private int excepted;
………………………………………………
@Parameters
public static Collection registerData() {
return Arrays.asList(new Object[][]{
{1L,"kevin",1,1}
});

public TestRegisterEventMaker(long sponsorId,String name,int type,int excepted)
{
this.sponsorId = sponsorId;
this.name = name;
this.type = type;
this.excepted = excepted;
}
………………………………………………

@Test
public void testGenerateDataSponsor() throws Exception {
………………………………………………
}

}

………………………………………………（此处省略N行代码）

• sponsorDao一直为null。。。。。。。 T_TPS：没使用Parameterized之前，还是可以成功注入的

2、问题解决

• 研究了一下Spring的东东，最后在官网上找到了TestContextManager这个问题在代码中加入，如下三行语句即可搞定：）privateTestContextManagertestContextManager;this.testContextManager = newTestContextManager(getClass());this.testContextManager.prepareTestInstance(this);例子：

………………………………
@RunWith(value=Parameterized.class)
public class TestRegisterEventMaker extends BaseSpringContextTestSupport {
………………………………………………
………………………………………………
@Autowired
private SponsorDaoImpl sponsorDao;

private TestContextManager testContextManager;

private long sponsorId;
private String name;
private int type;
private int excepted;
………………………………………………

@Parameters
public static Collection registerData() {
return Arrays.asList(new Object[][]{
{1L,"kevin",1,1}
});

public TestRegisterEventMaker(long sponsorId,String name,int type,int excepted)
{
this.sponsorId = sponsorId;
this.name = name;
this.type = type;
this.excepted = excepted;
}
………………………………………………

@Test
public void testGenerateDataSponsor() throws Exception {

this.testContextManager = new TestContextManager(getClass());
//需要try...catch的，注意（或直接像我一样Exception）
this.testContextManager.prepareTestInstance(this);
………………………………………………
}
}
