mybatis的insert返回主键

Java代码  

1. <insert id="insert" useGeneratedKeys="true" keyProperty="id" parameterType="com.model.OperationBookList" >  
2.    insert into operation_book_list (id, name, introduce,   
3.      category, state, up_date,   
4.      stop_date, down_date, modify_date  
5.      )  
6.    values (#{id,jdbcType=BIGINT}, #{name,jdbcType=VARCHAR}, #{introduce,jdbcType=VARCHAR},   
7.      #{category,jdbcType=VARCHAR}, #{state,jdbcType=CHAR}, #{upDate,jdbcType=TIMESTAMP},   
8.      #{stopDate,jdbcType=TIMESTAMP}, #{downDate,jdbcType=TIMESTAMP}, #{modifyDate,jdbcType=TIMESTAMP}  
9.      )  
10.  </insert>  

 在insert属性里增加useGeneratedKeys="true" keyProperty="id"
