Java spring mybatis MySQL 编写短信模板增删改查，使用SMStemplateDTO作为实体类名称，数据库字段有seq_no，template_id,push_plan_tp_cd,template_name,template_content,creator_no,create_time,modifier_no,mod_time,opror_instno,需要使用mapper.xml，mapper，controller，servive，serviceimpl，dto，controller需要使用public restresponse并抛出异常生成错误代码

好的，下面是代码实现。

首先是SMSTemplateDTO实体类：

public class SMSTemplateDTO {
    private Integer seqNo;
    private String templateId;
    private String pushPlanTpCd;
    private String templateName;
    private String templateContent;
    private String creatorNo;
    private Date createTime;
    private String modifierNo;
    private Date modTime;
    private String oprorInstno;

    // getter和setter方法省略
}

接下来是Mapper.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.example.mapper.SMSTemplateMapper">
    
    <!-- 查询短信模板列表 -->
    <select id="getSMSTemplateList" resultType="com.example.dto.SMSTemplateDTO">
        SELECT seq_no AS seqNo, template_id AS templateId, push_plan_tp_cd AS pushPlanTpCd, template_name AS templateName, template_content AS templateContent, creator_no AS creatorNo, create_time AS createTime, modifier_no AS modifierNo, mod_time AS modTime, opror_instno AS oprorInstno
        FROM t_sms_template
        ORDER BY seq_no
    </select>
    
    <!-- 根据seq_no查询短信模板 -->
    <select id="getSMSTemplateBySeqNo" parameterType="int" resultType="com.example.dto.SMSTemplateDTO">
        SELECT seq_no AS seqNo, template_id AS templateId, push_plan_tp_cd AS pushPlanTpCd, template_name AS templateName, template_content AS templateContent, creator_no AS creatorNo, create_time AS createTime, modifier_no AS modifierNo, mod_time AS modTime, opror_instno AS oprorInstno
        FROM t_sms_template
        WHERE seq_no = #{seqNo}
    </select>
    
    <!-- 插入短信模板 -->
    <insert id="insertSMSTemplate" parameterType="com.example.dto.SMSTemplateDTO">
        INSERT INTO t_sms_template (seq_no, template_id, push_plan_tp_cd, template_name, template_content, creator_no, create_time, modifier_no, mod_time, opror_instno)
        VALUES (#{seqNo}, #{templateId}, #{pushPlanTpCd}, #{templateName}, #{templateContent}, #{creatorNo}, #{createTime}, #{modifierNo}, #{modTime}, #{oprorInstno})
    </insert>
    
    <!-- 更新短信模板 -->
    <update id="updateSMSTemplate" parameterType="com.example.dto.SMSTemplateDTO">
        UPDATE t_sms_template
        SET template_id = #{templateId}, push_plan_tp_cd = #{pushPlanTpCd}, template_name = #{templateName}, template_content = #{templateContent}, modifier_no = #{modifierNo}, mod_time = #{modTime}, opror_instno = #{oprorInstno}
        WHERE seq_no = #{seqNo}
    </update>
    
    <!-- 删除短信模板 -->
    <delete id="deleteSMSTemplate" parameterType="int">
        DELETE FROM t_sms_template
        WHERE seq_no = #{seqNo}
    </delete>
    
</mapper>

然后是Mapper接口：

public interface SMSTemplateMapper {
    
    List<SMSTemplateDTO> getSMSTemplateList();
    
    SMSTemplateDTO getSMSTemplateBySeqNo(int seqNo);
    
    void insertSMSTemplate(SMSTemplateDTO smsTemplate);
    
    void updateSMSTemplate(SMSTemplateDTO smsTemplate);
    
    void deleteSMSTemplate(int seqNo);
    
}

接下来是Service实现类：

@Service
public class SMSTemplateServiceImpl implements SMSTemplateService {
    
    @Autowired
    private SMSTemplateMapper smsTemplateMapper;

    @Override
    public List<SMSTemplateDTO> getSMSTemplateList() {
        return smsTemplateMapper.getSMSTemplateList();
    }

    @Override
    public SMSTemplateDTO getSMSTemplateBySeqNo(int seqNo) {
        return smsTemplateMapper.getSMSTemplateBySeqNo(seqNo);
    }

    @Override
    public void insertSMSTemplate(SMSTemplateDTO smsTemplate) {
        smsTemplateMapper.insertSMSTemplate(smsTemplate);
    }

    @Override
    public void updateSMSTemplate(SMSTemplateDTO smsTemplate) {
        smsTemplateMapper.updateSMSTemplate(smsTemplate);
    }

    @Override
    public void deleteSMSTemplate(int seqNo) {
        smsTemplateMapper.deleteSMSTemplate(seqNo);
    }

}

最后是Controller：

@RestController
@RequestMapping("/smsTemplate")
public class SMSTemplateController {
    
    @Autowired
    private SMSTemplateService smsTemplateService;

    @GetMapping("/list")
    public RestResponse<List<SMSTemplateDTO>> getSMSTemplateList() {
        List<SMSTemplateDTO> smsTemplateList = smsTemplateService.getSMSTemplateList();
        return RestResponse.success(smsTemplateList);
    }
    
    @GetMapping("/{seqNo}")
    public RestResponse<SMSTemplateDTO> getSMSTemplateBySeqNo(@PathVariable int seqNo) {
        SMSTemplateDTO smsTemplate = smsTemplateService.getSMSTemplateBySeqNo(seqNo);
        if (smsTemplate == null) {
            throw new BusinessException("短信模板不存在");
        }
        return RestResponse.success(smsTemplate);
    }
    
    @PostMapping("/")
    public RestResponse<Void> insertSMSTemplate(@RequestBody SMSTemplateDTO smsTemplate) {
        smsTemplateService.insertSMSTemplate(smsTemplate);
        return RestResponse.success();
    }
    
    @PutMapping("/{seqNo}")
    public RestResponse<Void> updateSMSTemplate(@PathVariable int seqNo, @RequestBody SMSTemplateDTO smsTemplate) {
        smsTemplate.setSeqNo(seqNo);
        smsTemplateService.updateSMSTemplate(smsTemplate);
        return RestResponse.success();
    }
    
    @DeleteMapping("/{seqNo}")
    public RestResponse<Void> deleteSMSTemplate(@PathVariable int seqNo) {
        SMSTemplateDTO smsTemplate = smsTemplateService.getSMSTemplateBySeqNo(seqNo);
        if (smsTemplate == null) {
            throw new BusinessException("短信模板不存在");
        }
        smsTemplateService.deleteSMSTemplate(seqNo);
        return RestResponse.success();
    }
    
}

其中RestResponse是自定义的响应类，用于封装返回给前端的数据和状态码。BusinessException是自定义的异常类，用于处理业务异常。
