将Spring从4.3.x降级到3.2.x后，Spock中的自动装配bean测试无效

Question

我将应用程序从Spring 4.x降级到3.x，现在当我在使用自动装配bean的spock中进行简单测试时，此bean为null。

@ContextConfiguration(classes = Configuration.class)
class SomeTestClass extends Specification {

    @Autowired
    SomeService someService

    def "someService"(){
         expect:
         someService.returnHelloWorld() == "Hello World" // (<- NullPointer)

    }
}

我的pom.xml文件：

<dependencies>
  <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>3.2.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>3.2.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy-all</artifactId>
            <version>2.4.12</version>
        </dependency>
        <dependency>
            <groupId>org.spockframework</groupId>
            <artifactId>spock-core</artifactId>
            <version>1.1-groovy-2.4</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.spockframework</groupId>
            <artifactId>spock-spring</artifactId>
            <version>1.1-groovy-2.4</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>3.2.1.RELEASE</version>
            <scope>test</scope>
        </dependency>
</dependencies>

在我降级后，还将spock-core / spring降级为0.6-groovy-1.8，并将groovy-all降为1.8，并触发我的测试，它引发了以下异常：

org.springframework.beans.factory.BeanCreationException：创建文件../SomeBean.class中定义的名称为“ someAnotherBean”的bean时出错：bean的实例化失败； 嵌套异常isorg.springframework.beans.BeanInstantiationException：无法实例化bean类[..SomeBean.class]：未找到默认构造函数； 嵌套的异常是java.lang.NoSuchMethodException：.. SomeBean。（）

这个bean包含构造函数，我曾经在类中初始化最终的结局：

@Component
@PropertySource("classpath:someproperties.properties")
public class HeaderFactory {

private final SomeObject someObject;

    public HeaderFactory(@Value("${someProperty1}") String someProperty1, @Value("${someProperty2}") String someProperty2) {
        SomeObject someObject = new SomeObject(someProperty1,someProperty2);
       this.someObject = someObject;
    }
}

在我升级春季版本之前，一切工作都很好。 有任何想法吗？

Answer 1

您可以创建一个配置类并在那里定义有问题的bean：

@Configuration
class MyConfig {

    @Value("${someProperty1}") String prop1;
    @Value("${someProperty2}") String prop2

    @Bean
    public SomeBean someBean() {
        SomeBean bean = new SomeBean(prop1, prop2);
        return bean;
    }
}

我通过以下方式解决了我的问题：

@Component
public class UrlBuilder {

    private final String host;
    private final String port;
    private final String protocol;

    @Autowired
    public UrlBuilder(Environment env) {
        this.protocol = env.getRequiredProperty("app.server.protocol").toLowercase();
        this.serverHost = env.getRequiredProperty("app.server.host");
        this.serverPort = env.getRequiredProperty("app.server.port", Integer.class);
    }
}
