mybatis generator默认生成 的注释太奇葩了，完全不能拿到生产去用，不过幸亏提供了接口可以自己扩展。长话短说，要生成如下的domain，
package com.demo.domain;/** test_mybatis */public class TestMybatis { /** 主键 */ private Integer id; /** 字段说明 */ private String name; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; }} id, name delete from test_mybatis where id = #{id,jdbcType=INTEGER} SELECT LAST_INSERT_ID() insert into test_mybatis (name) values (#{name,jdbcType=VARCHAR})SELECT LAST_INSERT_ID() insert into test_mybatisname, #{name,jdbcType=VARCHAR}, update test_mybatis where id = #{id,jdbcType=INTEGER} name = #{name,jdbcType=VARCHAR}, update test_mybatis set name = #{name,jdbcType=VARCHAR} where id = #{id,jdbcType=INTEGER}
同时mapper.xml中也不要注释，可通过更改org.mybatis.generator.internal.DefaultCommentGenerator，并重新编译实现，如下：
