MongoDB 读写分离——SpringBoot读写分离

application.yml

  data:
    mongodb:
      uri: mongodb://127.0.0.1:27017,127.0.0.1:27018,127.0.0.1:27019/fecg_dev?slaveOk=true&replicaSet=rs0&write=1&readPreference=secondaryPreferred&connectTimeoutMS=300000

权限配置比较麻烦，演示先不配置

@Test
void MongoTest() throws InterruptedException {

    Param param = new Param();
    param.setCustodyOrderNo("THOTH2021");
    List<UserData> list = new ArrayList<>();
    for (int i = 0; i < 3; i++) {
        UserData userData = new UserData();
        userData.setDataTime(System.currentTimeMillis());
        userData.setDataValue(i);
        userData.setCreateTime(new Date());
        list.add(userData);
    }
    param.setUserDataList(list);
    mongoTemplate.insert(param.getUserDataList(), StrUtil.format("{}", param.getCustodyOrderNo()));
    Set<String> collectionList = mongoTemplate.getCollectionNames();
    for (String name : collectionList) {
        logger.info(name);
    }
}
