springboot+vue前后端分离

使用vue前端访问spring boot后台api，实现跨域访问，前后端分离。

后台提供json数据

import com.ftest.springboot.entity.Area;
import com.ftest.springboot.repository.CgRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping("/cg")
public class AreaController {
    @Autowired
    private CgRepository cgRepository;

    @GetMapping("/findall")
    public List<Area> findAll(){
        return cgRepository.findAll();
    }

    @GetMapping("/findall/{page}/{size}")
    public Page<Area> findAll1(@PathVariable int page, @PathVariable int size){

        PageRequest request=PageRequest.of(page,size);
        return cgRepository.findAll(request);
    }
}

 前端接收

data() {
    return {
        pagesize:'',//分页页码
        total:'',//总数
        tableData: []//数据
    }
},
created() {
    const _this=this;
    axios.get('http://localhost:8888/cg/findall/'+'0'+'/10').then(function (resp) {
        _this.tableData=resp.data.content
        _this.total=resp.data.totalElements
        _this.pagesize=resp.data.size
        // console.log(resp)
    })
}
