mapper文件中返回主键:
<insert id="insert" parameterType="com.za.cls.model.CompanyLeaseInfo" > <selectKey resultType="java.lang.Integer" keyProperty="id" order="AFTER" > SELECT LAST_INSERT_ID() </selectKey> insert into company_lease_info (name, code, business_licence, oper_name, oper_phone, card_no, province_code, province_name, city_code, city_name, area_code, area_name, addr_detail, founded_time, contact_realname, contact_phone, contact_email, manager_id, open_account_status, status, create_time, modify_time) values (#{name,jdbcType=VARCHAR}, #{code,jdbcType=VARCHAR}, #{businessLicence,jdbcType=VARCHAR}, #{operName,jdbcType=VARCHAR}, #{operPhone,jdbcType=VARCHAR}, #{cardNo,jdbcType=VARCHAR}, #{provinceCode,jdbcType=VARCHAR}, #{provinceName,jdbcType=VARCHAR}, #{cityCode,jdbcType=VARCHAR}, #{cityName,jdbcType=VARCHAR}, #{areaCode,jdbcType=VARCHAR}, #{areaName,jdbcType=VARCHAR}, #{addrDetail,jdbcType=VARCHAR}, #{foundedTime,jdbcType=VARCHAR}, #{contactRealname,jdbcType=VARCHAR}, #{contactPhone,jdbcType=VARCHAR}, #{contactEmail,jdbcType=VARCHAR}, #{managerId,jdbcType=INTEGER}, #{openAccountStatus,jdbcType=BIT}, #{status,jdbcType=TINYINT}, #{createTime,jdbcType=TIMESTAMP}, #{modifyTime,jdbcType=TIMESTAMP}) </insert>
在service层,调用这个方法后,根据getId方法可以获取主键。但在web层,controller的方法里,却获取的是null。
原因:web层和service层是通过dubbo调用的,其对象不是同一个,故获取不到主键。
解决方法:在service层返回主键,web层直接获取主键,而不是通过对象的getId方法获取。
