【log】AOP配置日志

直接代码

QueryService.java接口

public interface QueryService {

    TbDiseases getTbDiseasesById(int id) throws ServerException;

}

QueryServiceImpl实现

public class QueryServiceImpl implements QueryService {
    
    @Autowired
    private TbDiseaseDao tbDiseaseDao;

    @Override
    public TbDiseases getTbDiseasesById(int id) throws ServerException {
        return  tbDiseaseDao.read(id);
    }    
}

ILogService.java接口

public interface ILogService {
    
    public void log();
    
    public void logArg(JoinPoint point);
    /**
     * 有参和返回值的方法
     * @param point
     * @param returnObj
     */
    public void logArgAndReturn(JoinPoint point,Object returnObj);
}

LogServiceImpl实现

public class LogServiceImpl implements ILogService {
    
    Logger logger = Logger.getLogger(LogServiceImpl.class);

    @Override
    public void log() {
        System.out.println("*************Log*******************");
    }

    @Override
    public void logArg(JoinPoint point) {
        //此方法返回的是一个数组，数组中包括request以及ActionCofig等类对象
        Object[] args = point.getArgs();
        String methodName = point.getSignature().getDeclaringTypeName();
        logger.info("Method:" + methodName + " " + point.getSignature().getName());
        String params = "";
        if (args != null) {
            for (Object obj : args) {
                params += obj.toString() + ", ";
            }
        }
        logger.info("param size:" + args.length + " === " + params);
    }

    @Override
    public void logArgAndReturn(JoinPoint point, Object returnObj) {
        //此方法返回的是一个数组，数组中包括request以及ActionCofig等类对象
        logger.info("Result: " + returnObj);
    }

}
