spring aop實現（使用者操作記錄，一場記錄）
第一步定義兩個註解：
Java程式碼 複製程式碼
package com.annotation;
import java.lang.annotation.*;
/**
*自定義註解 攔截Controller
*/
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemControllerLog {
String description() default "";
}
package com.annotation;
import java.lang.annotation.*;
/**
*自定義註解 攔截service
*/
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemServiceLog {
String description() default "";
}
第二步建立一個切點類：
Java程式碼 複製程式碼
package com.annotation;
import com.model.Log;
import com.model.User;
import com.service.LogService;
import com.util.DateUtil;
import com.util.JSONUtil;
import com.util.SpringContextHolder;
import com.util.WebConstants;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import java.lang.reflect.Method;

if (joinPoint.getArgs() != null && joinPoint.getArgs().length > 0) {

/**

第三步把Controller的代理權交給cglib
-
在例項化ApplicationContext的時候需要加上
Xml程式碼 複製程式碼
aop:aspectj-autoproxy/
在呼叫Controller的時候AOP發揮作用所以在SpringMVC的配置檔案里加上
Xml程式碼 複製程式碼
