【spring】【spring mvc】【spring boot】获取spring cloud项目中所有spring mvc的请求资源

实现的方法：

1.在父级项目中 或者 每个微服务都引用的项目中添加实体类Resource

2.在父级项目中 或者 每个为服务都引用的项目中写一个工具类，作用是用来获取请求资源

3.在每一个微服务的启动类添加注解@RestController ,并且写一个请求方法调用 工具类的请求资源的方法

4.将获取到的JSON字符串 保存在文件中

5.最后,在需要存储这些信息到数据库中的对应微服务 提供一个请求方法，参数就传递这一个一个的JSON字符串，而请求方法做的事情就是解析JSON，并批量保存到对应数据表中

1.先提供一个状态这些结果的实体Resource.java

package com.pisen.cloud.luna.core.utils.beans;

public class Resource {

    public static final Integer GET_RESOURCE = 1;

    public static final Integer OTHER_RESOURCE = 2;

    public static final Integer ENABLE = 1;//启用

    public static final Integer DISENABLE = 0;//禁用

    private String path;//资源URL

    private String name;//资源名

    private String msName;//资源所属微服务

    private Integer type;//资源类型 1代表数据资源 2代表功能资源

    private Integer enable;//是否启用 0 禁用 1 启用

    private String user;//资源被使用对象

    private String remark;//资源备注

    public String getPath() {
        return path;
    }

    public void setPath(String path) {
        this.path = path;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getMsName() {
        return msName;
    }

    public void setMsName(String msName) {
        this.msName = msName;
    }

    public Integer getType() {
        return type;
    }

    public void setType(Integer type) {
        this.type = type;
    }

    public String getUser() {
        return user;
    }

    public void setUser(String user) {
        this.user = user;
    }

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark;
    }

    public Resource(String path, String name, String msName, Integer type, String user, String remark,Integer enable) {
        this.path = path;
        this.name = name;
        this.msName = msName;
        this.type = type;
        this.user = user;
        this.remark = remark;
        this.enable = enable;
    }
}

2.同样在 所有微服务都能引用到的 地方 提供一个工具类MappingResourceUtil.java

package com.pisen.cloud.luna.core.utils;

        if (servletContext == null)
        {
            return null;
        }
        WebApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(servletContext);

        for (HandlerMapping handlerMapping : allRequestMappings.values())
        {
            //本项目只需要RequestMappingHandlerMapping中的URL映射
            if (handlerMapping instanceof RequestMappingHandlerMapping)
            {

                    HandlerMethod mappingInfoValue = requestMappingInfoHandlerMethodEntry.getValue();

                    PatternsRequestCondition patternsCondition = requestMappingInfo.getPatternsCondition();
                    String requestUrl = patternsCondition.getPatterns() != null && patternsCondition.getPatterns().size()>0 ?
                            patternsCondition.getPatterns().stream().collect(Collectors.toList()).get(0).toString() : null;

                    RequestMethodsRequestCondition methodCondition = requestMappingInfo.getMethodsCondition();

                    if (requestType == null){
                        continue;

                    Class<?>[] methodParamTypes = mappingInfoValue.getMethod().getParameterTypes();

                    String name = getResourceName(requestType,requestMethodName);
                    Integer type = getType(requestType);
                    String path = msName+":"+requestUrl;
                    String user = getUser(requestUrl);
                    Integer enable = Resource.ENABLE;
                    Resource resource = new Resource(path,name,msName,type,user,null,enable);

                    requestToMethodItemList.add(resource);
                }
                break;
            }
        }

        return requestToMethodItemList;
    }

    /**
     * GET 代表数据资源 1
     * 其他 代表功能资源 2
     * @param type
     * @return
     */
    public static Integer getType(String type){
        return "GET".equals(type) ? Resource.GET_RESOURCE : Resource.OTHER_RESOURCE;
    }

    /**

        requestMethodName = requestMethodName.toLowerCase();
        if ("GET".equals(requestType)){
            return ResourceConfig.GET+requestMethodName;
        }else{
            if (requestMethodName.contains("page")){
                return ResourceConfig.PAGE+requestMethodName;
            }
            if(requestMethodName.contains("list")){

            }
            if (requestMethodName.contains("update")){

                return ResourceConfig.FIND+requestMethodName;
            }

            return requestMethodName;

        }
    }

    /**
     * 获取资源使用者身份

     * @return
     */
    public static String getUser(String requestUrl){
        if (StringUtils.isNotBlank(requestUrl)){

            String[] pathArr = requestUrl.split("/");

            if (pathArr.length > 0 ){
                if ("ten".equals(pathArr[1])){
                    return ResourceConfig.USER_TEN;
                }
                if ("admin".equals(pathArr[1])) {
                    return ResourceConfig.USER_ADMIN;
                }
                if ("member".equals(pathArr[1])){
                    return ResourceConfig.USER_MEMBER;
                }
                if ("free".equals(pathArr[1])){
                    return ResourceConfig.USER_FREE;
                }
                if ("dealer".equals(pathArr[1])){
                    return ResourceConfig.USER_DEALER;
                }
            }
        }
        return "未知使用者";

    }

}

以及一个配置类:ResourceConfig.java

package com.pisen.cloud.luna.core.utils.beans;

public class ResourceConfig {

    //资源名说明关键字
   public final static String GET = "获取";
    public final static String INIT = "初始化操作";
    public final static String VERIFY = "校验";
    public final static String DELETE = "删除操作";
    public final static String PAGE = "分页查询";
    public final static String INSERT = "插入操作";
    public final static String FIND = "查找";
    public final static String UPDATE = "更新操作";
    public final static String ENABLE = "启用判断";
    public final static String ADD = "添加操作";
    public final static String LIST = "集合";

    //各微服务网关别名

    public final static String MS_ACCOUNT = "ms-account";
    public final static String MS_ADMIN = "ms-admin";
    public final static String MS_DEALER = "ms-dealer";
    public final static String MS_EVENT_CENTER = "ms-event-center";
    public final static String MS_GOODS = "ms-goods";
    public final static String MS_INTEGRAL = "ms-integral";
    public final static String MS_MEMBER = "ms-member";
    public final static String MS_CODE = "ms-code";
    public final static String MS_TEN = "ms-ten";
    public final static String MS_ZHONGQI = "ms-zhongqi";
    public final static String MS_PAPER = "ms-paper";
    public final static String MS_TASK_LIST = "ms-task-list";

    //各使用者角色
   public final static String USER_ADMIN = "管理员";
   public final static String USER_TEN = "租户";
   public final static String USER_DEALER = "经销商";
   public final static String USER_FREE = "所有人";
   public final static String USER_MEMBER = "会员";

}

3.然后就可以在每一个微服务的启动类上加注解,加下面这段代码,然后启动这个微服务,访问就能拿到这个微服务下的所有请求资源 为一个JSON字符串了

举个例子,我现在获取这个微服务的所有请求资源:【红色部分就是 任意粘贴到每一个启动类的代码】【紫色部分就是需要更改的每一个不同微服务的不同服务名】

package pisen.cloud.luna.ms.account;

import com.alibaba.fastjson.JSON;
import com.pisen.cloud.luna.core.result.AjaxResult;
import com.pisen.cloud.luna.core.utils.MappingResourceUtil;

import com.pisen.cloud.luna.core.utils.beans.Resource;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.feign.EnableFeignClients;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

@EnableDiscoveryClient
@SpringBootApplication
@EnableFeignClients
@EnableTransactionManagement // 启注解事务管理，等同于xml配置方式的
@RestController
public class PisenLunaMSAccountApp {

    public static void main(String[] args) {
//        String str = MappingResourceUtil.getMappingList(PisenLunaMSAccountApp.class);

        SpringApplication.run(PisenLunaMSAccountApp.class, args);
    }

    @RequestMapping("/test/index")
    public AjaxResult<String> getAccout(HttpServletRequest request){
        AjaxResult<String> result = new AjaxResult<>();
        List<Resource> list = MappingResourceUtil.getMappingList(request,"ms-account");

        String account = JSON.toJSONString(list);

        result.initTrue(account);
        return result;
    }
}

然后启动本微服务后，postman请求即可：

4.将请求到的  JSON字符串，保存下来一会用

使用postman请求下来的字符串 如上 会有\

保存下来如下:

记得最后在编辑器中将\全部替换掉 否则 JSON转化会出问题

在sublime text中

将所有的\"替换成 "即可

替换完成 内容如下:

5.最后，在想要将这些JSON字符串转化为数据库数据的微服务中，提供一个批量插入的方法，然后将JSON字符串当作参数传入即可[controller中的请求方法]

@Override
    @RequestMapping("batchInsert2")
    public AjaxResult<List<Resource>> batchInsert2(@RequestBody String  json) {
        AdminUser adminUser = AdminUser.createFeignUser("insert-resource");
        String adminUid = adminUser.getUid();
        AjaxResult<List<Resource>> res = new AjaxResult<>();
        json = JSONObject.parseObject(json).getString("json");
        List<Resource> list = JSONArray.parseArray(json,Resource.class);
        for (Resource resource : list) {
            resource.setEnabledFlag(1);
            resource.setUid(LunaIDUtil.uid());
            resource.setCreateDate(new Date());
            resource.setUpdateDate(new Date());
            resource.setUpdateId(adminUid);
            resource.setCreateId(adminUid);
            resource.setUrl(resource.getPath());
        }
        sysUserService.batchInsert(list);
        res.initTrue(list);
        return res;
    }

Resource如下:

package com.pisen.cloud.luna.ms.tenement.base.domain;

import javax.persistence.*;
import java.util.Date;

@Entity
@Table(uniqueConstraints = {
        @UniqueConstraint(columnNames = "uid")
})
public class Resource {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;// 主键 自增

    @Column(nullable = false)
    private String uid; //业务主键

    @Column(nullable = false, updatable = false)
    private Date createDate = new Date();// 创建时间

    @Column(nullable = false)
    private Date updateDate = new Date();// 修改时间

    @Column(nullable = false)
    private String createId;// 创建人id

    @Column(nullable = false)
    private String updateId;// 修改人id

    private Integer enabledFlag;// 是否启用 1启用 0禁用

    private String remark;// 备注

    private String name;//资源名

    private String url;//资源URL

    private String path;// 资源URL

    private String msName;//资源所属微服务

    private Integer type;//资源类型 1代表数据资源 2代表功能资源

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getUid() {
        return uid;
    }

    public String getPath() {
        return path;
    }

    public void setPath(String path) {
        this.path = path;
    }

    public void setUid(String uid) {
        this.uid = uid;
    }

    public Date getCreateDate() {
        return createDate;
    }

    public void setCreateDate(Date createDate) {
        this.createDate = createDate;
    }

    public Date getUpdateDate() {
        return updateDate;
    }

    public void setUpdateDate(Date updateDate) {
        this.updateDate = updateDate;
    }

    public String getCreateId() {
        return createId;
    }

    public void setCreateId(String createId) {
        this.createId = createId;
    }

    public String getUpdateId() {
        return updateId;
    }

    public void setUpdateId(String updateId) {
        this.updateId = updateId;
    }

    public Integer getEnabledFlag() {
        return enabledFlag;
    }

    public void setEnabledFlag(Integer enabledFlag) {
        this.enabledFlag = enabledFlag;
    }

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public String getMsName() {
        return msName;
    }

    public void setMsName(String msName) {
        this.msName = msName;
    }

    public Integer getType() {
        return type;
    }

    public void setType(Integer type) {
        this.type = type;
    }
}

批量插入方法 使用JPA的save()即可，使用mybatis的批量插入也可以

使用postman请求地址如下:【注意请求的格式，post请求，参数格式也需要注意】

完成！！！！！！！

===========================================================================================

收集到另外一种方法，更简单：

直接在controller中加上一个方法，请求即可：

@RequestMapping(value="getUrlMapping")
    public Object getUrlMapping(HttpServletRequest request) {
        WebApplicationContext wc = getWebApplicationContext(request.getSession().getServletContext());
        RequestMappingHandlerMapping rmhp = wc.getBean(RequestMappingHandlerMapping.class);
        Map<RequestMappingInfo, HandlerMethod> map = rmhp.getHandlerMethods();
        for (Iterator<RequestMappingInfo> iterator = map.keySet().iterator(); iterator
                .hasNext();) {
            RequestMappingInfo info = iterator.next();
            System.out.println(info.getConsumesCondition());
            System.out.println(info.getCustomCondition());
            System.out.println(info.getHeadersCondition());
            System.out.println(info.getMethodsCondition());
            System.out.println(info.getParamsCondition());
            System.out.println(info.getPatternsCondition());
            System.out.println(info.getProducesCondition());

            System.out.println("===");

            HandlerMethod method = map.get(info);
            System.out.println(method.getMethod().getName() + "--");
            System.out.println();
        }
        return null;
    }
