调用post请求方式的feign接口怎么传递多个参数，包含对象和字符串

news2024/11/16 11:40:16

今天尝试把自己原来的项目上的权限管理相关的类抽离开来，并建立一个统一的权限管理平台，然后项目中要用到的权限相关资源通过feigin请求权限平台的对应接口获取。

现在有一个需求，页面上有一个一键获取资源权限的按钮，点击一下，在后台完成控制器接口的扫描，自动添加对应资源（先从数据库删除原来的资源）。

这个接口的代码

package cn.edu.sgu.www.mhxysy.service.system.impl;

import cn.edu.sgu.www.mhxysy.base.Pager;
import cn.edu.sgu.www.mhxysy.entity.system.Permission;
import cn.edu.sgu.www.mhxysy.mapper.system.PermissionMapper;
import cn.edu.sgu.www.mhxysy.pager.system.PermissionPager;
import cn.edu.sgu.www.mhxysy.service.system.PermissionService;
import cn.edu.sgu.www.mhxysy.util.ResourceScanner;
import cn.edu.sgu.www.mhxysy.util.StringUtils;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * @author heyunlin
 * @version 1.0
 */
@Service
public class PermissionServiceImpl implements PermissionService {
    @Value("${spring.application.name}")
    private String SERVICE_NAME;

    private final PermissionMapper mapper;
    private final ResourceScanner resourceScanner;

    public PermissionServiceImpl(PermissionMapper mapper, ResourceScanner resourceScanner) {
        this.mapper = mapper;
        this.resourceScanner = resourceScanner;
    }

    @Override
    public void init() throws ClassNotFoundException {
        // 删除指定服务的权限
        mapper.deleteByService(SERVICE_NAME);

        // 扫描路径
        String basePackage = "cn.edu.sgu.www.mhxysy.controller";

        // 获取扫描结果
        List<Permission> resources = resourceScanner.scan(basePackage);

        // 保存资源到数据库
        for (Permission permission : resources) {
            if (permission.getName() != null) {
                mapper.insert(permission);
            }
        }
    }

}

ResourceScanner这个类负责扫描controller包下的所有控制器的信息并封装成一个个Permission。

扫描的操作是在当前项目下完成，权限平台的接口只需要完成权限的删除和新权限的添加。

重构后的代码：

package cn.edu.sgu.www.mhxysy.service.system.impl;

import cn.edu.sgu.www.mhxysy.base.Pager;
import cn.edu.sgu.www.mhxysy.entity.system.Permission;
import cn.edu.sgu.www.mhxysy.feign.FeignService;
import cn.edu.sgu.www.mhxysy.mapper.system.PermissionMapper;
import cn.edu.sgu.www.mhxysy.pager.system.PermissionPager;
import cn.edu.sgu.www.mhxysy.service.system.PermissionService;
import cn.edu.sgu.www.mhxysy.util.ResourceScanner;
import cn.edu.sgu.www.mhxysy.util.StringUtils;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**
 * @author heyunlin
 * @version 1.0
 */
@Service
public class PermissionServiceImpl implements PermissionService {
    @Value("${spring.application.name}")
    private String SERVICE_NAME;

    private final FeignService feignService;
    private final ResourceScanner resourceScanner;
    private final PermissionMapper permissionMapper;

    public PermissionServiceImpl(
        FeignService feignService,
        ResourceScanner resourceScanner,
        PermissionMapper permissionMapper
    ) {
        this.feignService = feignService;
        this.permissionMapper = permissionMapper;
        this.resourceScanner = resourceScanner;
    }

    @Override
    public void init() throws ClassNotFoundException {
        // 删除指定服务的权限
        permissionMapper.deleteByService(SERVICE_NAME);

        // 扫描路径
        String basePackage = "cn.edu.sgu.www.mhxysy.controller";

        // 获取扫描结果
        List<Permission> resources = resourceScanner.scan(basePackage);

        feignService.init(SERVICE_NAME, resources);
    }

}

feign接口

package cn.edu.sgu.www.mhxysy.feign;

import cn.edu.sgu.www.mhxysy.component.MenuTree;
import cn.edu.sgu.www.mhxysy.entity.system.Permission;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

import java.util.List;
import java.util.Map;

/**
 * @author heyunlin
 * @version 1.0
 */
@FeignClient(name = "authority", fallback = FeignFallback.class)
public interface FeignService {

    @RequestMapping(value = "/menu/listTree", method = RequestMethod.GET)
    Map<String, List<MenuTree>> listTree(@RequestParam("userId") String userId);

    @RequestMapping(value = "/permission/init", method = RequestMethod.POST)
    void init(String service, List<Permission> permissions);
}

这里直接通过post请求传递两个参数，权限平台对应的接口代码如下

package cn.edu.sgu.www.authority.controller;

import cn.edu.sgu.www.authority.entity.Permission;
import cn.edu.sgu.www.authority.pager.PermissionPager;
import cn.edu.sgu.www.authority.restful.JsonResult;
import cn.edu.sgu.www.authority.restful.PageResult;
import cn.edu.sgu.www.authority.service.PermissionService;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@Api(tags = "权限控制器类")
@RequestMapping(path = "/permission", produces = "application/json;charset=utf-8")
public class PermissionController {
    private final PermissionService permissionService;

    @Autowired
    public PermissionController(PermissionService service) {
        this.permissionService = service;
    }

    @ApiOperation("初始化权限列表")
    @RequestMapping(value = "/init", method = RequestMethod.POST)
    public JsonResult<Void> init(String service, List<Permission> permissions) throws ClassNotFoundException {
        permissionService.init(service, permissions);

        return JsonResult.success("权限列表初始化完成。");
    }

}

业务层代码

package cn.edu.sgu.www.authority.service.impl;

import cn.edu.sgu.www.authority.base.Pager;
import cn.edu.sgu.www.authority.entity.Permission;
import cn.edu.sgu.www.authority.mapper.PermissionMapper;
import cn.edu.sgu.www.authority.pager.PermissionPager;
import cn.edu.sgu.www.authority.service.PermissionService;
import cn.edu.sgu.www.authority.util.StringUtils;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * @author heyunlin
 * @version 1.0
 */
@Service
public class PermissionServiceImpl implements PermissionService {
    private final PermissionMapper mapper;

    public PermissionServiceImpl(PermissionMapper mapper) {
        this.mapper = mapper;
    }

    @Override
    public void init(String service, List<Permission> permissions) {
        // 删除指定服务的权限
        mapper.deleteByService(service);

        // 保存资源到数据库
        for (Permission permission : permissions) {
            if (permission.getName() != null) {
                mapper.insert(permission);
            }
        }
    }

}

这个时候项目启动直接报错，看到这一堆报错是不是头都大了

其实遇到这种情况，只需要找到问题的根源，也就是最后一个cause by

这里的关键是这一句，方法有太多body参数，显然，post请求只能有一个请求体

Method has too many Body parameters

既然这样，我们就把两个参数封装成一个类不就行了：创建一个PermissionDTO类

package cn.edu.sgu.www.mhxysy.dto.system;

import cn.edu.sgu.www.mhxysy.entity.system.Permission;
import lombok.Data;

import java.util.List;

/**
 * @author heyunlin
 * @version 1.0
 */
@Data
public class PermissionDTO {
    /**
     * 服务名称
     */
    String service;

    /**
     * 权限列表
     */
    List<Permission> permissions;
}

修改之后的代码

package cn.edu.sgu.www.mhxysy.service.system.impl;

import cn.edu.sgu.www.mhxysy.base.Pager;
import cn.edu.sgu.www.mhxysy.dto.system.PermissionDTO;
import cn.edu.sgu.www.mhxysy.entity.system.Permission;
import cn.edu.sgu.www.mhxysy.feign.FeignService;
import cn.edu.sgu.www.mhxysy.mapper.system.PermissionMapper;
import cn.edu.sgu.www.mhxysy.pager.system.PermissionPager;
import cn.edu.sgu.www.mhxysy.service.system.PermissionService;
import cn.edu.sgu.www.mhxysy.util.ResourceScanner;
import cn.edu.sgu.www.mhxysy.util.StringUtils;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * @author heyunlin
 * @version 1.0
 */
@Service
public class PermissionServiceImpl implements PermissionService {
    @Value("${spring.application.name}")
    private String SERVICE_NAME;

    private final FeignService feignService;
    private final ResourceScanner resourceScanner;
    private final PermissionMapper permissionMapper;

    public PermissionServiceImpl(
        FeignService feignService,
        ResourceScanner resourceScanner,
        PermissionMapper permissionMapper
    ) {
        this.feignService = feignService;
        this.permissionMapper = permissionMapper;
        this.resourceScanner = resourceScanner;
    }

    @Override
    public void init() throws ClassNotFoundException {
        // 扫描路径
        String basePackage = "cn.edu.sgu.www.mhxysy.controller";
        // 获取扫描结果
        List<Permission> permissions = resourceScanner.scan(basePackage);

        PermissionDTO permissionDTO = new PermissionDTO();

        permissionDTO.setService(SERVICE_NAME);
        permissionDTO.setPermissions(permissions);

        feignService.init(permissionDTO);
    }

}

 对应的feign接口参数修改为一个PermissionDTO对象

package cn.edu.sgu.www.mhxysy.feign;

import cn.edu.sgu.www.mhxysy.component.MenuTree;
import cn.edu.sgu.www.mhxysy.dto.system.PermissionDTO;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

import java.util.List;
import java.util.Map;

/**
 * @author heyunlin
 * @version 1.0
 */
@FeignClient(name = "authority", fallback = FeignFallback.class)
public interface FeignService {

    @RequestMapping(value = "/menu/listTree", method = RequestMethod.GET)
    Map<String, List<MenuTree>> listTree(@RequestParam("userId") String userId);

    @RequestMapping(value = "/permission/init", method = RequestMethod.POST)
    void init(PermissionDTO permissionDTO);
}

权限平台的相关代码修改

控制器

@ApiOperation("初始化权限列表")
@RequestMapping(value = "/init", method = RequestMethod.POST)
public JsonResult<Void> init(PermissionDTO permissionDTO) throws ClassNotFoundException {
    permissionService.init(permissionDTO);

    return JsonResult.success("权限列表初始化完成。");
}

业务层

@Override
public void init(PermissionDTO permissionDTO) {
    String service = permissionDTO.getService();
    List<Permission> permissions = permissionDTO.getPermissions();

    // 删除指定服务的权限
    if (service != null) {
        mapper.deleteByService(service);
    }

    if (!permissions.isEmpty()) {
        // 保存到数据库
        for (Permission permission : permissions) {
            if (permission.getName() != null) {
                mapper.insert(permission);
            }
        }
    }
}

然后重新启动两个项目，启动没有报错了，然后再测试一下，点击初始化按钮，还是报错了

直接看权限平台的报错信息，NPE，没有获取到请求体中对应的参数
