对于初学mybatis的同学来说,在后台删除多条数据是一个比较棘手的事情,在这里分享一下自己操作过的后台删除数据

Controller层
@RequestMapping(value = "/delMore", method = RequestMethod.POST,headers = "Accept=application/json")
public QueryDada delMore(@RequestBody Integer [] list) throws Exception {
    QueryDada queryDada = new QueryDada();

    try {
        userServiceImpl.delMore(list);
        queryDada.setCode(Constans.SUCCESS_CODE);
        queryDada.setMessage(Constans.QUERY_USER_MESSAGE);
    } catch (Exception e) {
        e.printStackTrace();
        queryDada.setCode(Constans.QUERY_USER_ERROR_MESSAGE);
        queryDada.setMessage(Constans.QUERY_USER_ERROR_MESSAGE);
    }
    return queryDada;
}
service层
public void delMore(Integer [] list) {
    userDao.delMore(list);
}
dao/mapper层
void delMore(Integer [] list);

mapper.xml
<delete id="delMore" parameterType="java.util.Arrays">
    delete from user
    where id in
    <foreach collection="array" index="index" item="item" open="(" separator="," close=")">
              #{item}
     </foreach>
</delete>

postman端

queryData类

public class QueryDada {
    private String code;
    private Object data;
    private String Message;

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public Object getData() {
        return data;
    }

    public void setData(Object data) {
        this.data = data;
    }

    public String getMessage() {
        return Message;
    }

    public void setMessage(String message) {
        Message = message;
    }
}
