来来回回瞅了半天，原来是sql语句错了

update user set username = #{username} and address = #{address} where id = #{id}

把 and 改成 逗号 , OK

update user set username = #{username} ， address = #{address} where id = #{id}

低级错误！！！sql语法错误

update语句，如果有更多的列,就用逗号连接，不是and

update 表名 set 字段名1 = 值1 , 字段名2 = 值2 , …. , 字段名n = 值n where 条件

注意：如果没有where条件，会将所有记录修改；

注意避免sql语句的语法错误，还是要习惯性地先在Navicat运行测试一下。。。
