Spring 3.2 @Configurable和@Autowire无法注入任何东西

Question

我想将一个SecureRandom实例注入到@Entity类中，但是当我在运行Tomcat的调试版时检查该值时，我只看到一个空值。我没有收到任何错误消息。

我已将spring-instrument-tomcat-3.2.5.RELEASE.jar放入C：\ apache-tomcat-7.0.40 \ lib中，它看起来很好。

Gradle.build文件

只是依赖

    def springVersion = '3.2.5.RELEASE'
    def springSecurityVersion = '3.2.0.RELEASE'
    def jacksonVersion = '2.3.0'

    def tomcatVersion = '7.0.11'

实体类

我删除了一些额外内容以使此示例更清晰。

@Entity
@Configurable(preConstruction = true, autowire = Autowire.BY_TYPE)
public class Invitation {

    @Id
    @GeneratedValue
    private int id;

    @Transient
    @Autowired
    private SecureRandom random;

    public Invitation(User owner, String inviteeEmail, String accessCode) {
        if(accessCode == null) {
            this.accessCode = generateAlphanumericAccessCode();
        } else {
            this.accessCode = accessCode;
        }
        this.owner = owner;
        this.inviteeEmail = inviteeEmail;
    }

    private String generateAlphanumericAccessCode() {
        return new BigInteger(130, random).toString(32);
    }

}

Java配置类

再次，删除额外内容以使其更清晰。

@Configuration
@EnableWebMvc
@ComponentScan(basePackageClasses = RootContextConfig.class)
@EnableTransactionManagement
@EnableWebSecurity
@EnableAsync
@EnableSpringConfigured
@EnableLoadTimeWeaving(aspectjWeaving = EnableLoadTimeWeaving.AspectJWeaving.ENABLED)
public class RootContextConfig extends WebMvcConfigurerAdapter {

    @Bean
    public SecureRandom secureRandom() {
        return new SecureRandom();
    }
}

Context.xml（位于webapp / META-INF中）

我的webapp部署到生产和开发中的根上下文。

<?xml version="1.0" encoding="UTF-8"?>
<Context>
    <Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/>
</Context>

Answer 1

原来我需要一个aop.xml，它需要位于src / main / resources / META-INF / aop.xml中。我认为它首先从WEB-INF / classes / META-INF / aop.xml中获取aop.xml。我认为次要的是来自春天的依赖。
