浏览器访问http://127.0.0.1:9000/business/admin/chapter/list?page=1&size=1出现http状态码400

Question

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Bad Request, status=400).

Required request body is missing: public com.course.server.dto.PageDto com.course.business.controller.admin.ChapterController.list(com.course.server.dto.PageDto)

org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: public com.course.server.dto.PageDto com.course.business.controller.admin.ChapterController.list(com.course.server.dto.PageDto)

vue：

<script>
export default {
  name: "chapter",
  data:function () {
    return {
      chapters:[]
    }
  },
  mounted: function() {
    let _this = this;
    _this.list();
    //sidebar 激活样式 方式一
    // this.$parent.activeSidebar("business-chapter-sidebar");

  },
  methods: {
    list() {
      let _this = this;
      _this.$ajax.post('http://127.0.0.1:9000/business/admin/chapter/list', {
        page: 1,
        size: 1
      }).then((response)=>{
        console.log("查询大章列表结果：", response);
        _this.chapters = response.data.list;
      })
    }
  }
}
</script>

ChapterController

@RestController
@RequestMapping("/admin/chapter")
public class ChapterController {

    private static final Logger LOG = LoggerFactory.getLogger(ChapterController.class);

    @Resource
    private ChapterService chapterService;

    @RequestMapping("/list")
    public PageDto list(@RequestBody PageDto pageDto) {
        LOG.info("pageDto: {}", pageDto);
        chapterService.getList(pageDto);
        return pageDto;
    }
}

不能直接在浏览器访问：http://127.0.0.1:9000/business/admin/chapter/list?page=1&size=1，这种方式的参数是拼在url里的，不是放在request body里，所以后端接收不到参数，就会报错：Required request body is missing:

9000端口是网关吧，你确定热部署重启成功了嘛

  还是不行，浏览器访问http://localhost:8080/business/chapter倒是能正常显示
