如何精简日志，只看SQL语句.

如何精简日志，只看ibatis SQL语句.
1.修改日志配置文件
log4j.rootLogger=debug, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%m%n

log4j.logger.net.rubyeye.xmemcached=error

log4j.logger.com.opensymphony.xwork2=error

log4j.logger.org.springframework=error

log4j.logger.com.google.code=error

log4j.logger.com.itv.ti.manager=error

log4j.logger.org.mybatis.spring=error

log4j.logger.org.apache.struts2=error

log4j.logger.com.jolbox.bonecp=error

log4j.logger.org.apache.ibatis.logging.slf4j.Slf4jImpl=error

log4j.logger.com.jolbox.bonecp.ConnectionHandle=error

log4j.logger.org.slf4j.impl.Log4jLoggerAdapter=error

log4j.logger.org.apache.log4j.Logger=error
2.修改PreparedStatementLogger
 public Object invoke(Object proxy, Method method, Object[] params) throws Throwable {

   if (EXECUTE_METHODS.contains(method.getName())) {

     String sql = statement.toString();

     for (Object paramVal : columnValues) {

      String dateType = paramVal.getClass().getSimpleName();

      if("String".equals(dateType)){

       sql = sql.replaceFirst("\\?", "'"+paramVal.toString()+"'");

      }else{

       sql = sql.replaceFirst("\\?", paramVal.toString());

      }

     }

     sql = sql.replaceAll("\n", " ");

     while(sql.indexOf("\t")!=-1){

      sql = sql.replaceAll("\t", " ");

     }

     while(sql.indexOf("  ")!=-1){

      sql = sql.replaceAll("  ", " ");

     }

     System.out.println(" "+sql);

  ｝

BaseJdbcLogger

修饰符改为public
private List<Object> columnValues = new ArrayList<Object>();
public List<Object> columnValues = new ArrayList<Object>();

３.去掉其它ibatis日志

 org.apache.ibatis.logging.jdbc.BaseJdbcLogger

   清空方法体

  protected void debug(String text) {

  

  }
