有没有一种方法可以使用Spring添加记录器实例?
有没有一种方法可以跟踪我的自定义代码中的每个方法调用?
我通常这样做:
package my.java.code;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class A {
// How to add this line with Spring ?
private static final Logger logger = LoggerFactory.getLogger(A.class);
public void A() {
// How to add this line with Spring ?
logger.trace("");
// Do something...
}
public void A(Object o) {
// How to add this line with Spring ?
logger.trace("{}", o);
// Do something...
}
public void method1() {
// How to add this line with Spring ?
logger.trace("");
// Do something...
}
public void method2(Object o) {
// How to add this line with Spring ?
logger.trace("{}", o);
// Do something...
}
}
有没有办法用Spring简化这个过程?
目标是:
避免重复代码
最佳答案
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/aop/spring-aop.xsd">
<bean id="customizableTraceInterceptor"
class="org.springframework.aop.interceptor.CustomizableTraceInterceptor">
<property name="enterMessage"
value="Entering $[targetClassName].$[methodName]($[argumentTypes] $[arguments])" />
<property name="exitMessage" value="Leaving $[methodName](): $[returnValue]" />
</bean>
<aop:config>
<aop:advisor advice-ref="customizableTraceInterceptor"
pointcut="execution(* fr.my.package.dao..*.*(..))" />
</aop:config>
</beans>
这有助于我跟踪
fr.my.package.dao
包中所有类的所有方法的每次调用。感谢@ m-deinum
