spring获取mybatis语句

 切面类：  import com.alibaba.fastjson.JSONObject; import com.tasu.server.utils.*; import lombok.extern.slf4j.Slf4j; import org.apache.ibatis.session.SqlSessionFactory; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.AfterReturning; import org.aspectj.lang.annotation.Around; 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.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import org.springframework.util.StringUtils; import org.springframework.web.context.request.RequestContextHolder; import org.springframework.web.context.request.ServletRequestAttributes;  import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.lang.reflect.Method; import java.util.*;  @Aspect @Component @Slf4j public class WebRequestAspect {     @Autowired     private SqlSessionFactory sqlSessionFactory;      @Pointcut("execution( * com.tasu.server..dao.*.*(..))")     public void logDao() {     }     @Before("logDao()")     public void before(JoinPoint joinPoint) throws Throwable {         // 接收到请求，记录请求内容         ServletRequestAttributes attributes = (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();         HttpServletRequest request = attributes.getRequest();          log.info("dao请求地址 : " + request.getRequestURL().toString());         log.info("dao请求类型 : " + request.getMethod());         log.info("dao实现方法: " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());         log.info("dao参数 : " + Arrays.toString(joinPoint.getArgs()));   

 //仅获取无参数语句 String sql =sqlSessionFactory.getConfiguration().getMappedStatement(joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName()).getBoundSql(null).getSql();

          //获取最终执行的sql语句         String sql=new MyBatisSqlUtils().execute(joinPoint.getSignature().getName(), joinPoint.getArgs(),sqlSessionFactory);       } }
