Vertx 接入MongoDB (九)

项目github地址：https://github.com/fotocj007/VertxWebApi

 

一：加入配置文件 mongodb.json

1 compile group: 'io.vertx', name: 'vertx-mongo-client', version: '3.9.8'
View Code
1 {
2   "sources": [
3     {"host": "10.0.205.199", "port": 27017, "db_name": "wsdemo","minPoolSize":5,"maxPoolSize": 10}
4   ],
5   "pools": 4
6 }
View Code

二：加载配置文件

 1 public class MongoDbConfig extends JsonObjectConfig {
 2     public JsonArray sources;
 3     public int poolSize;
 4 
 5     public MongoDbConfig(Vertx vertx, String path){
 6         super(vertx,path);
 7     }
 8 
 9     @Override
10     public void parse(JsonObject jsonObject) {
11         sources = jsonObject.getJsonArray("sources");
12         poolSize = jsonObject.getInteger("pools",8);
13     }
14 }
View Code

 

三：链接mongodb

 1 public class MongoPool {
 2     private int poolSize;
 3 
 4     private Vertx vertx;
 5 
 6     private List<JsonObject> sourceList;
 7 
 8     private Map<String,List<MongoClient>> pools;
 9 
10     public List<String> dbList;
11 
12     public MongoPool(Vertx vertx, int poolS, List<JsonObject> sourceList){
13         this.vertx = vertx;
14         this.poolSize = poolS;
15         this.sourceList = sourceList;
16         pools = new HashMap<>(poolS);
17         dbList = new ArrayList<>(2);
18         initPool();
19     }
20 
21     private void initPool() {
22         for (JsonObject config : sourceList) {
23             String db = config.getString("db_name");
24 
25             String connectionString = String.format("mongodb://%s:%d/%s",
26                     config.getString("host"), config.getInteger("port"),
27                     db);
28 
29             JsonObject options = new JsonObject()
30                     .put("connection_string", connectionString)
31                     .put("minPoolSize", config.getInteger("minPoolSize"))
32                     .put("maxPoolSize",config.getInteger("maxPoolSize"));
33 
34             // look for username, password and auth_source
35             Optional.ofNullable(config.getString("username", null))
36                     .ifPresent(user -> options.put("username", user));
37             Optional.ofNullable(config.getString("password", null))
38                     .ifPresent(pass -> options.put("password", pass));
39 
40             List<MongoClient> list = new ArrayList<>();
41             for (int j = 1; j <= poolSize; j++) {
42                 list.add(MongoClient.create(vertx, options));
43             }
44 
45             dbList.add(db);
46             pools.put(db, list);
47         }
48     }
49 
50     public MongoClient getClient(String db){
51         return pools.get(db).get(ThreadLocalRandom.current().nextInt(poolSize));
52     }
53 
54     public void close(){
55         for(List<MongoClient> list : pools.values()){
56             for(MongoClient client : list){
57                 client.close();
58             }
59         }
60     }
61 }
View Code

 

四：添加个帮助类

 1 public class PlayerMongo{
 2     protected static Logger logger = LoggerFactory.getLogger(PlayerMongo.class);
 3 
 4     private final String DB_NAME;
 5 
 6     protected MongoPool mongoDbPool;
 7 
 8     public PlayerMongo(MongoPool mongoPool) {
 9         this.DB_NAME = mongoPool.dbList.get(0);
10         this.mongoDbPool = mongoPool;
11     }
12 
13     public void findPlayerById(String collection,long playerId,Handler<AsyncResult<PlayerInfo>> handler) {
14         JsonObject jsonQuery = new JsonObject().put("_id",playerId);
15         mongoDbPool.getClient(DB_NAME).findOne(collection, jsonQuery, null, res -> {
16             if (res.succeeded()) {
17                 JsonObject reData = res.result();
18 
19                 long id = reData.getLong("_id",playerId);
20                 reData.remove("_id");
21 
22                 PlayerInfo info = new JsonObject(reData.toString()).mapTo(PlayerInfo.class);
23                 info.setId(id);
24 
25                 handler.handle(Future.succeededFuture(info));
26             }else {
27                 handler.handle(Future.failedFuture(res.cause()));
28                 logger.error("findById error",res.cause());
29             }
30         });
31     }
32 
33     public void updateAndInsert(String collection, long playerId, JsonObject upData, Handler<AsyncResult<Boolean>> handler){
34         JsonObject find = new JsonObject().put("_id",playerId);
35         JsonObject upInsert = new JsonObject()
36                 .put("$set",upData);
37 
38         //更新，没有时插入
39         mongoDbPool.getClient(DB_NAME).findOneAndUpdateWithOptions(collection, find, upInsert,
40                 new FindOptions(),
41                 new UpdateOptions().setUpsert(true), res -> {
42             if (res.succeeded()) {
43                 handler.handle(Future.succeededFuture(true));
44             } else {
45                 handler.handle(Future.failedFuture(res.cause()));
46                 logger.error("updateAndInsert error",res.cause());
47             }
48         });
49     }
50 }
View Code

 

五：Dao管理类

 1 public class MongoManager {
 2     private MongoPool mongoPool;
 3 
 4     private PlayerMongo playerMongo;
 5 
 6     public MongoManager(MongoPool mySQLPool){
 7         this.mongoPool = mySQLPool;
 8         init();
 9     }
10 
11     private void init(){
12         playerMongo = new PlayerMongo(mongoPool);
13     }
14 
15     public PlayerMongo getPlayerMongo(){
16         return playerMongo;
17     }
18 }
View Code

 

六：修改configure，初始化mongodb.

 1 public class Configure {
 2     private static final Configure ourInstance = new Configure();
 3 
 4     public Configure() {
 5     }
 6 
 7     public static Configure getInstance() {
 8         return ourInstance;
 9     }
10 
11     protected Vertx vertx;
12 
13     public MysqlConfig mysqlConfig;
14     private MySQLUtil mySQLPool;
15     public DaoManager daoManager;
16 
17     private RedisConfig redisConfig;
18     private RedisPool redisPool;
19     public RedisUtil redisUtil;
20 
21     private MongoDbConfig mongoDbConfig;
22     private MongoPool mongoPool;
23     public MongoManager mongoManager;
24 
25     public void init(Vertx vertx){
26         this.vertx = vertx;
27 
28         initHandler();
29 
30         loadConfig();
31 
32         initDb();
33         initRedis();
34         initMongoDb();
35     }
36 
37     private void initHandler(){
38         HandlerManager.getInstance().addHandler(new DemoHandler());
39     }
40 
41     /**
42      *  加载db和Redis配置文件
43      */
44     protected void loadConfig(){
45         mysqlConfig = new MysqlConfig(vertx, "res/mysql.json");
46         redisConfig = new RedisConfig(vertx, "res/redis.json");
47         mongoDbConfig = new MongoDbConfig(vertx,"res/mongodb.json");
48     }
49 
50     protected void initDb(){
51         List<JsonObject> list = new ArrayList<>();
52         for(int i = 0; i< mysqlConfig.configs.size();i++){
53             list.add(mysqlConfig.configs.getJsonObject(i));
54         }
55         mySQLPool = new MySQLUtil(vertx,2,list);
56 
57         daoManager = new DaoManager(mysqlConfig,mySQLPool);
58     }
59 
60     /**
61      *  初始化Redis
62      */
63     protected void initRedis(){
64         redisPool = new RedisPool(vertx,redisConfig);
65         redisUtil = new RedisUtil(redisPool);
66     }
67 
68     private void initMongoDb(){
69         List<JsonObject> list = new ArrayList<>();
70         for(int i = 0; i< mongoDbConfig.sources.size();i++){
71             list.add(mongoDbConfig.sources.getJsonObject(i));
72         }
73         mongoPool = new MongoPool(vertx,mongoDbConfig.poolSize,list);
74         mongoManager = new MongoManager(mongoPool);
75     }
76 
77     public void closeResource(){
78         if(mySQLPool != null){
79             mySQLPool.close();
80         }
81         if(redisPool != null){
82             redisPool.close();
83         }
84 
85         if(mongoPool != null){
86             mongoPool.close();
87         }
88     }
89 }

七：测试一下，修改DemoHandler

        PlayerInfo info = new PlayerInfo();
        info.setId(3242353465L);
        info.setUserName("kkkkkdd");
        info.setAge(100);
        
        PlayerMongo playerMongo = Configure.getInstance().mongoManager.getPlayerMongo();
        playerMongo.updateAndInsert("playerColl",info.getId(),new JsonObject(JsonObject.mapFrom(info).toString()),res -> {
            System.out.println(res.result());


            //查询
            playerMongo.findPlayerById("playerColl",info.getId(),ress -> {
                System.out.println(ress);

            });
        });
