WxJava for Solon - 咱也不知道为啥要写

?

应 Solon 技术交流群里小伙伴的要求，我分享下在 Solon 中使用 WxJava 的经验、类库。

---

具体实现

1. 提供统一的 Yaml 配置

package cn.edu.hnuahe.mountain.common.providers;

import org.noear.solon.annotation.Component;
import org.noear.solon.annotation.Init;
import org.noear.solon.core.Aop;
import org.yaml.snakeyaml.DumperOptions;
import org.yaml.snakeyaml.Yaml;

/**
 * @author 颖
 */
@Component
public class YamlProvider extends ServiceProvider {

    @Init
    @Override
    public void bootstrap() {
        DumperOptions options = new DumperOptions();
        options.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
        options.setDefaultScalarStyle(DumperOptions.ScalarStyle.PLAIN);
        Aop.wrapAndPut(Yaml.class, new Yaml(options));
    }

}

1. 提供 WxService 统一管理器

package cn.edu.hnuahe.mountain.common.utils;

import me.chanjar.weixin.cp.api.WxCpService;
import org.noear.solon.annotation.Component;

import java.util.concurrent.ConcurrentHashMap;

/**
 * @author 颖
 */
@Component
public class WxCpClient extends ConcurrentHashMap<String, WxCpService> {

    public WxCpService get() {
        return this.get("default");
    }

}

1. WxConfigDefault 注入提供器

package cn.edu.hnuahe.mountain.common.providers;

import cn.edu.hnuahe.mountain.common.utils.WxCpClient;
import me.chanjar.weixin.cp.api.WxCpService;
import me.chanjar.weixin.cp.api.impl.WxCpServiceImpl;
import me.chanjar.weixin.cp.config.impl.WxCpDefaultConfigImpl;
import me.chanjar.weixin.cp.message.WxCpMessageRouter;
import org.noear.solon.Solon;
import org.noear.solon.annotation.Component;
import org.noear.solon.annotation.Init;
import org.noear.solon.annotation.Inject;
import org.noear.solon.cloud.CloudClient;
import org.noear.solon.cloud.model.Config;
import org.noear.solon.core.Aop;
import org.yaml.snakeyaml.Yaml;

import java.util.LinkedHashMap;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;

/**
 * @author 颖
 */
@Component
public class WxCpServiceProvider extends ServiceProvider {

    @Inject
    Yaml yaml;
    @Inject
    WxCpClient wxCpClient;

    public static class WxCpConfig extends ConcurrentHashMap<String, WxCpDefaultConfigImpl> {}

    @Init
    @Override
    public void bootstrap() {
        Config rawConfig = CloudClient.config().pull(Solon.cfg().appGroup(), "wxCp.yaml");
        WxCpConfig configs = this.yaml.loadAs(rawConfig.value(), WxCpConfig.class);

        configs.forEach((name, config) -> {
            WxCpService service = new WxCpServiceImpl();
            service.setWxCpConfigStorage(config);
            // 注册到企业微信客户端管理器
            this.wxCpClient.put(name, service);
        });

        WxCpMessageRouter router = new WxCpMessageRouter(
                this.wxCpClient.get()
        );
        Aop.wrapAndPut(WxCpMessageRouter.class, router);
    }

}

[scode type="blue"]步骤2与步骤3共同解决了一个大问题，就是一个企业微信小程序可能需要拥有多种身份的问题。比如，访问企业微信通讯录就需要基于 通讯录同步 小程序的身份进行操作。[/scode]

1. 一个 Test，用于生成需要的 wxCp.yaml 配置

package cn.edu.hnuahe.mountain.common.providers;

import me.chanjar.weixin.cp.config.impl.WxCpDefaultConfigImpl;
import me.chanjar.weixin.cp.config.impl.WxCpRedissonConfigImpl;
import org.junit.jupiter.api.Test;
import org.noear.solon.core.Aop;
import org.yaml.snakeyaml.DumperOptions;
import org.yaml.snakeyaml.Yaml;

import static org.junit.jupiter.api.Assertions.*;

class WxCpServiceProviderTest {

    @Test
    void generateConfig() {
        DumperOptions options = new DumperOptions();
        options.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
        options.setDefaultScalarStyle(DumperOptions.ScalarStyle.PLAIN);
        Yaml yaml = new Yaml(options);

        WxCpDefaultConfigImpl defaultConfig = new WxCpDefaultConfigImpl();
        defaultConfig.setCorpId("123");
        defaultConfig.setCorpSecret("456");
        defaultConfig.setAgentId(789);
        WxCpDefaultConfigImpl contactsConfig = new WxCpDefaultConfigImpl();
        contactsConfig.setCorpId("987");
        contactsConfig.setCorpSecret("654");

        WxCpServiceProvider.WxCpConfig config = new WxCpServiceProvider.WxCpConfig();
        config.put("default", defaultConfig);
        config.put("contacts", contactsConfig);

        System.out.println(yaml.dump(config));
    }

}

1. 一个简单的使用案例

package cn.edu.hnuahe.mountain.gateway.http.controller;

import cn.edu.hnuahe.mountain.common.entities.models.User;
import cn.edu.hnuahe.mountain.common.http.controller.BaseController;
import cn.edu.hnuahe.mountain.common.mappers.UserMapper;
import cn.edu.hnuahe.mountain.common.utils.WxCpClient;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import me.chanjar.weixin.common.error.WxErrorException;
import me.chanjar.weixin.cp.bean.Gender;
import me.chanjar.weixin.cp.bean.WxCpUser;
import me.chanjar.weixin.cp.bean.article.NewArticle;
import me.chanjar.weixin.cp.bean.message.WxCpMessage;
import me.chanjar.weixin.cp.bean.message.WxCpMessageSendResult;
import org.noear.solon.annotation.Controller;
import org.noear.solon.annotation.Inject;
import org.noear.solon.annotation.Mapping;
import org.noear.solon.core.handle.MethodType;

import java.util.List;

/**
 * @author 颖
 */
@Controller
@Mapping(value = "/wechat")
public class WeChatController {

    @Inject
    WxCpClient wxCpClient;

    @Mapping(value = "sendMessage", method = MethodType.ALL)
    public WxCpMessageSendResult sendMessage() throws WxErrorException {
        NewArticle part1 = new NewArticle();
        part1.setUrl("https://www.baidu.com/");
        part1.setPicUrl("https://pc-index-skin.cdn.bcebos.com/hiphoto/56868369122.jpg?x-bce-process=image/crop,x_0,y_0,w_1728,h_1080");
        part1.setDescription("Is Really A Happy Day");
        part1.setTitle("Happy Day");

        WxCpMessage message = WxCpMessage.NEWS()
                .agentId(this.wxCpClient.get().getWxCpConfigStorage().getAgentId())
                .toUser("2102160202008")
                .addArticle(part1)
                .build();

        return this.wxCpClient.get()
                .getMessageService()
                .send(message);

    }

}
