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}, </if> <if test="idno!= null and idno != ''"> idno = #{idno}, </if> <if test="name!= null and name != ''"> name = #{name}, </if> <if test="sex!= null and sex != ''"> sex = #{sex}, </if> <if test="phone!= null and phone != ''"> phone = #{phone}, </if> <if test="birth!= null and birth != ''"> birth = DATE_FORMAT(#{birth},'%Y-%m-%d'), </if> <if test="nation != null and nation != ''"> nation = #{nation}, </if> <if test="degree!= null and degree != ''"> degree = #{degree}, </if> <if test="nativeType!= null and nativeType != ''"> native_type = #{nativeType}, </if> <if test="nativePlace!= null and nativePlace != ''"> native_place = #{nativePlace}, </if> <if test="address!= null and address != ''"> address = #{address}, </if> <if test="firstJobYear!= null and firstJobYear != ''"> first_job_year = #{firstJobYear}, </if> <if test="empType!= null and empType != ''"> emp_type = #{empType}, </if> <if test="empForm!= null and empForm != ''"> emp_form = #{empForm}, </if> <if test="startDate!= null and startDate != ''"> start_date = DATE_FORMAT(#{startDate},'%Y-%m-%d'), </if> </trim> </update>
