方法一:
在实体类里面将set方法里面将数据类型转为Date
public void setBirth(String birth) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
try {
this.birth = sdf.parse(birth);
} catch (ParseException e) {
e.printStackTrace();
}
}
这样就可以了
注意在修改是判断是否为空的时候不能写birth!=“”,否则报java.util.Date and java.lang.String 的错
<if test="birth!= null">
birth = #{birth},
</if>
方法二:
实体类改为String类型,在xml里面改数据类型
<insert id="insert" parameterType="实体类">
INSERT INTO
table(id,idtype,idno,name,sex,phone,birth,nation,degree,native_type,native_place,address,first_job_year,emp_type,emp_form,start_date)
VALUES(#{id},#{idtype},#{idno},#{name},#{sex},#{phone},DATE_FORMAT(#{birth},'%Y-%m-%d'),#{nation},#{degree},#{nativeType},#{nativePlace},#{address},#{firstJobYear},#{empType},#{empForm},DATE_FORMAT(#{startDate},'%Y-%m-%d'))
</insert>-->
<update id="update" parameterType="实体类">
update table
<trim prefix="SET" suffixOverrides="," suffix="WHERE id = #{id}" >
<if test="idtype!= null and idtype != ''">
idtype = #{idtype},

</trim>
</update>
