在上一篇“SpringBoot 使用@Aspect进行日志管理（基于反射代理模式+注解Log）”的基础上，添加注解进行日志管理升级版
1、修改日志注解类

/** * 日志注解 * Created by 陈梓平 on 2017/9/7. */@Target({ElementType.PARAMETER, ElementType.METHOD})@Retention(RetentionPolicy.RUNTIME)@Documentedpublic @interface JournalLog {    /** 要执行的操作类型比如：add **/     int operationType() default -1;    /** 要执行的模块名称如：Carouse **/     int modularTypeName() default -1;     /**注解说明*/     String xplain() default "";     /**判断类型*/     boolean checkBoolean() default false;    /**注解说明数组*/    String[] xplainArray() default "";}

2、添加注解工具类

/** * 注解工具类 * Created by 陈梓平 on 2017/9/11. */public class AnnotationUtils {    /**日志输出*/    private static final Logger logger = LoggerFactory.getLogger(AnnotationUtils.class);    private static AnnotationUtils mInstance;    public AnnotationUtils() {    }    public static AnnotationUtils get() {        if (mInstance == null) {            synchronized (AnnotationUtils.class) {                if (mInstance == null) {                    mInstance = new AnnotationUtils();                }            }        }        return mInstance;    }    /**     * 获取注解属性值信息     * @param className 类名     * @param methodName 方法名     * @param annotationClass 注解类     * @param attrName 注解属性名     * @throws NotFoundException     */    public static Object getAnnotationAttr(String className,String methodName,Class<?> annotationClass,String attrName) throws NotFoundException, NoSuchMethodException {        Object value = null;        if (StringUtils.isBlank(className))            return value;        if (StringUtils.isBlank(methodName))            return value;        if (annotationClass==null)            return value;        if (StringUtils.isBlank(attrName))            return value;        ClassPool pool = ClassPool.getDefault();        //获取要修改的类的所有信息        CtClass ct = pool.get(className);        CtMethod ctMethod = ct.getDeclaredMethod(methodName);        MethodInfo methodInfo = ctMethod.getMethodInfo();        //获取注解属性        AnnotationsAttribute attribute = (AnnotationsAttribute) methodInfo.getAttribute(AnnotationsAttribute.visibleTag);        String annotationName = annotationClass.getName();        Method operationType = annotationClass.getDeclaredMethod(attrName);        Class<?> returnType = operationType.getReturnType();        if (attribute!=null){            //获取注解            Annotation annotation = attribute.getAnnotation(annotationName);            if (annotation!=null){                //获取注解的值                if (int.class.isAssignableFrom(returnType)){                    IntegerMemberValue memberValue = (IntegerMemberValue) annotation.getMemberValue(attrName);                    if (memberValue!=null)                        value =  memberValue.getValue() ;                }                if (String.class.isAssignableFrom(returnType)){                    StringMemberValue memberValue = (StringMemberValue) annotation.getMemberValue(attrName);                    if (memberValue!=null)                        value = memberValue .getValue() ;                }                if (boolean.class.isAssignableFrom(returnType)){                    BooleanMemberValue memberValue = (BooleanMemberValue) annotation.getMemberValue(attrName);                    if (memberValue!=null)                         value = memberValue.getValue() ;                }                if (String[].class.isAssignableFrom(returnType)){                    ArrayMemberValue memberValue = (ArrayMemberValue) annotation.getMemberValue(attrName);                    if (memberValue!=null){                        MemberValue[] strValueArray = memberValue.getValue();                        String[] strValueA = new String[strValueArray.length];                        for (int i = 0;i<strValueArray.length;i++){                            StringMemberValue  stringMemberValue = (StringMemberValue) strValueArray[i];                            strValueA[i] = stringMemberValue.getValue();                        }                        value = strValueA;                    }                }            }        }        return value;    }    /**     * 修改注解属性     * @param className 类名     * @param methodName 方法名     * @param annotationClass 注解名     * @param attrName 属性名     * @param value 修改值     * @throws NotFoundException     */    public static boolean updateAnnotationAttr(String className,String methodName,Class<?> annotationClass,String attrName,Object value) throws NotFoundException, NoSuchMethodException {        if (StringUtils.isBlank(className))            return false;        if (StringUtils.isBlank(methodName))            return false;        if (annotationClass==null)            return false;        if (StringUtils.isBlank(attrName))            return false;        if (value==null)            return false;        ClassPool pool = ClassPool.getDefault();        //获取需要修改的类        CtClass ct = pool.get(className);        CtMethod minInfo = ct.getDeclaredMethod(methodName);        MethodInfo methodInfo = minInfo.getMethodInfo();        ConstPool cp = methodInfo.getConstPool();        AnnotationsAttribute attribute = new AnnotationsAttribute(cp, AnnotationsAttribute.visibleTag);        String annotationName = annotationClass.getName();        Method operationType = annotationClass.getDeclaredMethod(attrName);        Class<?> returnType = operationType.getReturnType();        Annotation annotation = new Annotation(annotationName, cp);        //修改名称为unitName的注解        if (annotation != null) {            if (String.class.isAssignableFrom(returnType))                annotation.addMemberValue(attrName, new StringMemberValue((String) value, cp));            else if (int.class.isAssignableFrom(returnType))                annotation.addMemberValue(attrName, new IntegerMemberValue(cp,(Integer)value));            else if (boolean.class.isAssignableFrom(returnType))                annotation.addMemberValue(attrName, new BooleanMemberValue((boolean) value, cp));            else if (String[].class.isAssignableFrom(returnType)){                String[] stres = (String[])value;                StringMemberValue[] elements = new StringMemberValue[stres.length];                for(int i=0;i<stres.length;i++)                    elements[i] = new StringMemberValue(stres[i],cp);                ArrayMemberValue amv = new ArrayMemberValue(cp);                amv.setValue(elements);                annotation.addMemberValue(attrName,amv);            }else                return false;            attribute.setAnnotation(annotation);            methodInfo.addAttribute(attribute);            return true;        }        return false;    }}

3、修改日志切面类

import com.chen.annotation.JournalLog;import com.chen.exception.CustomException;import com.chen.staticInfos.StaticInfo;import com.chen.utils.AnnotationUtils;import com.chen.utils.JournalUtils;import javassist.NotFoundException;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.annotation.After;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Pointcut;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;import org.springframework.transaction.annotation.Transactional;/** * 日志切面 * Created by 陈梓平 on 2017/9/11. */@Component@Aspectpublic class JournalAspect {    /**日志输出*/    private static final Logger logger = LoggerFactory.getLogger(JournalAspect.class);    /**日志工具类*/    @Autowired    private JournalUtils aspectJournalUtils;    /**service层切面*/    private final String POINT_CUT = "execution(* com.chen.service..*(..))";    @Pointcut(POINT_CUT)    private void pointcut(){}    /**     * 后置最终通知（目标方法只要执行完了就会执行后置通知方法）     * 日志管理     * @param joinPoint     */    @After(value = "pointcut()")    @Transactional    public void doAfterAdvice(JoinPoint joinPoint) throws CustomException, ClassNotFoundException, NotFoundException, NoSuchMethodException {        String className = joinPoint.getTarget().getClass().getName();        String methodName = joinPoint.getSignature().getName();        int modulerType = -1;        int opreationType = -1;        modulerType = (int) AnnotationUtils.get().getAnnotationAttr(className, methodName, JournalLog.class, StaticInfo.AOP_LOG_ATTR_NAME1);        opreationType = (int) AnnotationUtils.get().getAnnotationAttr(className, methodName, JournalLog.class, StaticInfo.AOP_LOG_ATTR_NAME2);        //3.添加日志        if (modulerType!=-1&&opreationType!=-1)            //TODO 3.1 从请求获取用户id            aspectJournalUtils.addJournalInfo(modulerType,opreationType, 10086);    }}
