Question

我正在使用带有Spring Data的Mongo DB，一切正常，直到我决定使用Spring AOP Aspects进行日志记录。这是我的弹簧配置，Person Service和LoggingAspect Code：

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

    <aop:aspectj-autoproxy  proxy-target-class="true"/>

   <bean id="loggingAspect" class="com.vaap.aop.LoggingAspect" />



</beans>


package com.vaap;

public class PersonService implements IPersonService {

    @Autowired
    MongoTemplate mongoTemplate;

    public static final String COLLECTION_NAME = "person";

    public void addPerson(Person person) {
        if (!mongoTemplate.collectionExists(Person.class)) {
            mongoTemplate.createCollection(Person.class);
        }
        person.setId(UUID.randomUUID().toString());

        // mongoTemplate.save(objectToSave, collectionName);

        // DBObject dbObject = (DBObject) JSON.parse(jsonStr);

        mongoTemplate.insert(person, COLLECTION_NAME);
    }

    public List<Person> listPerson() {

        return mongoTemplate.findAll(Person.class, COLLECTION_NAME);
    }

    public String getPersonJSON() {
        BasicQuery basicQuery = new BasicQuery("{'status':'Active'}");

        return mongoTemplate.find(basicQuery, String.class, COLLECTION_NAME)
                .toString();
    }

    public void deletePerson(Person person) {
        mongoTemplate.remove(person, COLLECTION_NAME);
    }

    public void updatePerson(Person person) {
        mongoTemplate.insert(person, COLLECTION_NAME);
    }
}

package com.vaap.aop;

import java.util.Arrays;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.AfterThrowing;

@Component
@Configurable
@Aspect
public class LoggingAspect {

    static final Logger log = LoggerFactory.getLogger(LoggingAspect.class);



    @AfterThrowing(pointcut = "execution(* *.*(..))", throwing = "e")
    public void logAfterThrowing(JoinPoint joinPoint, Throwable e) {
        log.error("An exception has been thrown in "
                + joinPoint.getSignature().getName() + "()");
        log.error("Cause :" + e.getCause());
    }

    @Around("execution(* *.*(..))")
    public Object logAround(ProceedingJoinPoint joinPoint) throws Throwable {
        log.info("The method " + joinPoint.getSignature().getName()
                + "() begins with " + Arrays.toString(joinPoint.getArgs()));
        try {
            Object result = joinPoint.proceed();
            log.info("The method " + joinPoint.getSignature().getName()
                    + "() ends with " + result);
            return result;
        } catch (IllegalArgumentException e) {
            log.error("Illegal argument "
                    + Arrays.toString(joinPoint.getArgs()) + " in "
                    + joinPoint.getSignature().getName() + "()");
            throw e;
        }
    }

}

如果我评论<aop:aspectj-autoproxy proxy-target-class="true"/>行，一切正常，否则我收到此错误：

Caused by: org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'mongoTemplate' defined in class path resource [SpringConfig.xml]: 
Cannot resolve reference to bean 'mongoDbFactory' while setting constructor argument; 
nested exception is org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'mongoDbFactory': Initialization of bean failed; 
nested exception is org.springframework.aop.framework.AopConfigException:

Common causes of this problem include using a final class or a non-visible class; 
nested exception is java.lang.IllegalArgumentException: Superclass has no null constructors but no arguments

我知道，这可能不是Spring问题，因为这是标准的CGI Lib行为，但如果我想使用XML配置并希望同时使用两者，弹簧数据与mongodb和spring aop进行日志记录，我还有什么选择。< / p>
