[置顶] 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) {
  
  }
