mybatis查不出数据

Question

下面是控制台打出的信息，可以看出mybatis明明知行了sql，参数也传进去了，为什么就是查不出呢？2017-04-22 19:31:09,755 [http-bio-8080-exec-9] DEBUG [Message.queryMessagesList] - ooo Using Connection [com.mysql.jdbc.JDBC4Connection@51df5caf]2017-04-22 19:31:09,756 [http-bio-8080-exec-9] DEBUG [Message.queryMessagesList] - ==>  Preparing: select id,command,description,content from message where 1=1 and COMMAND=? 2017-04-22 19:31:09,756 [http-bio-8080-exec-9] DEBUG [Message.queryMessagesList] - ==> Parameters: 查看(String)
