Question

当我在数据库连接上出错时，我需要记录它（使用数据库名称和尝试连接数据库的用户名，不需要记录密码），我在我的应用程序上使用Sprig-Mybatis

任何想法如何做到这一点？

没有其他特殊方法可以做，因为java中的简单try / catch会让你获得预期。例如，我调用mybatis映射器方法的简单程序：

    try{
    List result = mapper.myBatisMapperMethod();//this is responsible to set up 
                                              //a connection and run a query
    }

假设上述调用由于身份验证无效而失败，请在下面说明我的密码错误连接异常我通常会进入mybatis：

Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Login failed for user 'applicationUsername'.)
        Caused by: org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Login failed for user 'applicationUsername'.)
            at org.apache.commons.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1225)
            at org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.java:880)
            at org.springframework.jdbc.datasource.DataSourceUtils.doGetConnection(DataSourceUtils.java:111)
            at org.springframework.jdbc.datasource.DataSourceUtils.getConnection(DataSourceUtils.java:77)
            ... 65 more
        Caused by: 
    com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'applicationUsername'.

我所做的是上面有一个简单的捕获尝试你可以捕获一个sql异常，但在这里我只使用异常。

 catch(Exception e){
        //Suppose you are using Log4j You can simply
        logger.error("This is my error log message"+e.getMessage());
        //The above will log any kind of exception including the authentication fail or you 
        can specifically log a particular kind of exception.Java wont log failed password it just logs the user who tried unless you explicitly want to log it.
    }
