SpringAOP日志配置
SpringAOP日志配置
配置文件配置
l 配置spring-mvc.xml
<aop:config proxy-target-class="true" />
<bean id="logInterceptor" class="com.sjzxywlkj.cplife.log.LogInterceptor" />
<!-- 使用xml配置aop -->
<!-- 强制使用cglib代理，如果不设置，将默认使用jdk的代理，但是jdk的代理是基于接口的 -->
<aop:config>
<!--定义切面 -->
<aop:aspect id="logAspect" ref="logInterceptor">
<!-- 定义切入点 (配置在com.sjzxywlkj.cplife.controller下所有的类在调用之前都会被拦截) -->
<aop:pointcut expression="execution(* com.sjzxywlkj.cplife.controller.*.*(..))"
id="logPointCut" />
<!--方法执行之前被调用执行的 -->
<aop:before method="before" pointcut-ref="logPointCut" /><!--一个切入点的引用 -->
<aop:after method="after" pointcut-ref="logPointCut" /><!--一个切入点的引用 -->
</aop:aspect>
</aop:config>
l 日志处理类
package com.sjzxywlkj.cplife.log;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class LogInterceptor {
private final Logger logger = LoggerFactory.getLogger(LogInterceptor.class);
// private static Logger logger =LoggerFactory.getLogger(LogInterceptor.class);
public void before() {
logger.info("login start!");
logger.debug("lllllllllllllllllllllll");
// System.out.println("qqqqqqqqqqqqqqqqqqqqq");
}
public void after() {
logger.info("login end!");
logger.debug("aaaaaaaaaaaaaaaaaaaaaaaaa");
// System.out.println("wwwwwwwwwwwwwwwwwwwwwwwwwww");
}
}
l log4j.properties日志文件配置
### 设置###
### 日志相应级别debug，输出位置 d,e
log4j.rootLogger = debug,D,E
### 输出DEBUG 级别以上的日志到=E://logs/log.log ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${webapp.root}/WEB-INF/logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
### 输出ERROR 级别以上的日志到=E://logs/error.log ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File =${webapp.root}/WEB-INF/logs/error.log
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern =%-d{yyyy-MM-dd HH\:mm\:ss} [ %t\:%r ] - [ %p ] %m%n
l web.xml配置日志
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:resources/log4j.properties</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
注解文件配置
l spring-mvc.xml文件配置
方法一
//扫描aop日志处理类
<context:component-scan base-package="com.sjzxywlkj.cplife.log" />
//开启aop
<aop:aspectj-autoproxy proxy-target-class="true" />
方法二
<bean id="logInterceptor" class="com.sjzxywlkj.cplife.log.LogInterceptor"></bean>
<aop:aspectj-autoproxy proxy-target-class="true"/>
l 日志切面类
package com.sjzxywlkj.cplife.log;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
@Aspect
@Component
public class LogInterceptor {
private final Logger logger = LoggerFactory.getLogger(LogInterceptor.class);
@Before(value = "execution(* com.sjzxywlkj.cplife.controller.*.*(..))")
public void before() {
logger.info("login start!");
System.out.println("lllllllllllllllllllll");
}
@After(value = "execution(* com.sjzxywlkj.cplife.controller.*.*(..))")
public void after() {
logger.info("login end!");
System.out.println("aaaaaaaaaaaaaaaaaaaaaaaaa");
}
}
基于自定义注解
l 配置文件设置
<context:component-scan base-package="com.sjzxywlkj.cplife.log"></context:component-scan>
<context:component-scan base-package="com.sjzxywlkj.cplife.annotation"></context:component-scan>
<aop:aspectj-autoproxy proxy-target-class="true">
</aop:aspectj-autoproxy>
l 自定义注解
package com.sjzxywlkj.cplife.annotation;
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log {
String oper() default "";
}
l 日志切面类
package com.sjzxywlkj.cplife.log;
import java.lang.reflect.Method;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import com.sjzxywlkj.cplife.annotation.Log;
@Aspect
@Component
public class LogInterceptor {
private final Logger logger = LoggerFactory.getLogger(LogInterceptor.class);
@Pointcut("@annotation(com.sjzxywlkj.cplife.annotation.Log)")
public void controllerAspect() {
}
@Before("controllerAspect()")
public void before(JoinPoint joinPoint) {
logger.info(getOper(joinPoint));
}
private String getOper(JoinPoint joinPoint) {
MethodSignature methodName = (MethodSignature) joinPoint.getSignature();
Method method = methodName.getMethod();
return method.getAnnotation(Log.class).oper();
}
}
l Controller注入
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private IUserService uService;
// 用户登录
@RequestMapping(value = "/login", method = RequestMethod.GET)
@ResponseBody
@Log(oper="user login")
public String login(){
return null;
}
