没有Spring Boot的Java Spring测试-错误java.lang.IllegalStateException：无法加载ApplicationContext

trzczy 发表于 Dev

裂缝：

我正在学习Java Spring框架。我刚开始。如我所读，当人们学习Spring时，最好从Spring开始，而不是从Spring Boot开始。我有一个非常简单的测试，即只显示一个字符串。我在一个教程中找到了该应用程序，但是它已经通过Spring Boot进行了测试，因此我尝试将其转换为Spring。但是随后引发了错误：java.lang.IllegalStateException: Failed to load ApplicationContext

请帮助我在没有Spring Boot的Spring中修复它。下面是日志和文件。

更新资料

我做了Siddharth Agrawal在他的回答中提到的更改，并且该更改有效。我还对代码进行了一些小删除，因此更改了3个文件：

./src/test/java/guru/springframework/dibestpractices/ControllerTest.java

package guru.springframework.dibestpractices;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { BpFinalConstructorController.class, BpServiceImpl.class })

public class ControllerTest {

    @Autowired
    BpFinalConstructorController bpFinalConstructorController;

    @Bean
    public BpService bpService() {
        return new BpServiceImpl();
    }

    @Test
    public void testFieldController() {
        System.out.println("A Best Practice Controller says: " + bpFinalConstructorController.saySomething());
    }
}

./src/main/java/guru/springframework/dibestpractices/BpFinalConstructorController.java

package guru.springframework.dibestpractices;

import lombok.RequiredArgsConstructor;

@RequiredArgsConstructor
public class BpFinalConstructorController {
    private final BpService bpService;

    public String saySomething() {
        return bpService.getHello();
    }
}

./src/main/java/guru/springframework/dibestpractices/BpServiceImpl.java

package guru.springframework.dibestpractices;

public class BpServiceImpl implements BpService {
    @Override
    public String getHello() {
        return "The Best Hello!";
    }
}
Siddharth Agrawal：

这是由于控制器的构造函数中的不满足依赖性。在您的控制器中：

@RequiredArgsConstructor
@Controller
@Component
public class BpFinalConstructorController {
    private final BpService bpService;

    public String saySomething() {
        return bpService.getHello();
    }
}

该@RequiredArgsConstructor注释动态生成此构造函数：

public BpFinalConstructorController(BpService bpService) {
    this.bpService = bpService;
}

因此，在测试类中，您需要为该类提供一个bean BpService。包括BpServiceImpl.class在您的测试中@ContextConfiguration，它应该可以工作。
