切入业务日志-创新互联

创建接口BizAnnotation.java

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
public @interface BizAnnotation {

    //操作模块
    String moduleName();
    //操作
    String option();

}

标记业务接口StudentService.java

import java.util.List;
import com.shenzhen.management.pojo.Student;
public interface StudentService {
public List getAllStudents();
@BizAnnotation(moduleName="Student Management",option="Add Student")
public void addStudent(Student student);
}

创建业务日志类BizLogger.java
