Java Spring开机测试配置

Spring boot test configuration

提问by sansari

I have a spring boot application with main class like below:

我有一个带有如下主类的 Spring Boot 应用程序：

@SpringBootApplication
public class Application {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

Now I want to test my services and created a base test class:

现在我想测试我的服务并创建了一个基础测试类：

@SpringApplicationConfiguration(Application.class)
public abstract class TestBase {
}

When I run my test I get exception:

当我运行测试时，出现异常：

Caused by: java.lang.IllegalArgumentException: Can not load an ApplicationContext with a NULL 'contextLoader'. Consider annotating your test class with @ContextConfiguration.
    at org.springframework.util.Assert.notNull(Assert.java:115)
    at org.springframework.test.context.TestContext.loadApplicationContext(TestContext.java:117)
    at org.springframework.test.context.TestContext.getApplicationContext(TestContext.java:148)

Then I change my base test class using ContextConfiguration

然后我使用 ContextConfiguration 更改我的基本测试类

@ContextConfiguration(classes = Application.class)
public abstract class TestBase {
}

This time I get DataSource initialization error. I am wondering why it is failing in first case and why in second case it does not load my application.propertieswhere I have configured datasource.

这次我收到 DataSource 初始化错误。我想知道为什么它在第一种情况下失败，为什么在第二种情况下它没有加载我配置数据源的application.properties。

Thank you!

谢谢！

You should use initializers.

您应该使用初始化程序。

Please refer the below questions.

请参考以下问题。

Something like that:

类似的东西：

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class ApplicationTest{

   @Autowired
   Foo foo; //whatever you are testing

   @Test
   public void FooTest() throws Exception{
     Foo f = foo.getFooById("22");
     assertEquals("9B", f.getCode); 
   }
 //TODO look into MockMVC for testing services
}

I faced the same issue it is because my ServletInitializer was in the different package. Problem resolved after correcting the package structure.

我遇到了同样的问题，因为我的 ServletInitializer 在不同的包中。更正包结构后问题已解决。

You will not find all this so simple as below :) Took long time to find out .

你不会发现这一切像下面这么简单:) 花了很长时间才找到。

Configuration:

配置：

@TestConfiguration
@PropertySource(value = "classpath:test.properties", encoding = "UTF-8")
public class GlobalConfig {

    @Bean(name = "JsonMapper")
    public JsonMapper jsonMapper() {

        return new JsonMapper();
    }

    @Bean(name = "ObjectMapper")
    public ObjectMapper objectMapper() {

        return new ObjectMapper();
    }

    @Bean(name = "Mapper")
    public Mapper dozer() {

        return new DozerBeanMapper();
    }

    @Bean(name = "Validator")
    public Validator validator() {

        return new DefaultValidatorAdapter();
    }

}
