宝兰德应用服务器微服务版本V11.5.0-接入ZooKeeper配置中心

本文介绍如何将宝兰德应用服务器微服务版本接入ZooKeeper配置中心，从配置中心获取配置文件并启动。本文档基于宝兰德应用服务器微服务版V11.5.0.007进行编写，若使用其他版本，请参考对应版本的用户手册。

宝兰德应用服务器微服务版本支持接入以下配置中心：

Nacos
ZooKeeper
ApolloConfig
宝兰德分布式配置中心BES Distributed Config Service，简称DCS

1. 接入ZooKeeper配置中心

1.1 接入ZooKeeper配置中心需要引入的依赖

groupId	artifactId	version	说明
com.bes.appserver	bes-lite-spring-boot-starter	11.5.0.007	嵌入式WEB容器实现
com.bes.appserver	bes-configprovider-spring-boot-starter	11.5.0.007	配置中心支持
org.apache.zookeeper	zookeeper	${zookeeper.version}	ZooKeeper客户端

1.2 加载ZooKeeperConfigProvider

在application.properites或者application.yml中配置如下选项触发加载ZooKeeperConfigProvider：

配置项	说明
server.bes.spring.boot.config-provider.class	指定为com.bes.enterprise.config.spring.boot.provider.ZooKeeperConfigProvider接入ZooKeeper配置中心

或者通过环境变量配置触发加载ZooKeeperConfigProvider：

export CONFIG_PROVIDER_CLASS=com.bes.enterprise.config.spring.boot.provider.ZooKeeperConfigProvider

1.3 ZooKeeperConfigProvider对应的配置项

配置项	说明
spring.cloud.zookeeper.connect-string	ZooKeeper配置中心的服务地址
spring.cloud.zookeeper.node	指定ZooKeeper中用于存储应用的application.yml或者application.properties的数据节点
spring.cloud.zookeeper.file-extension	指定配置的格式，可选值为：yaml，yml，properties

1.4 接入ZooKeeper配置中心示例

搭建和使用ZooKeeper集群请参考ZooKeeper相关手册。

1.4.1 在ZooKeeper配置中心添加宝兰德应用服务器微服务版使用的配置

在一个已有的ZooKeeper集群中添加一个数据节点/zookeeper/my_application.yml，其内容如下：

server:
  port: 9080
  address: 0.0.0.0
  bes:
    maxThreads: 200
    minSpareThreads: 2
    jdbc:
      name: myDataSource
      enabled: true
      username: mysql_username
      password: mysql_password
      url: jdbc:mysql://localhost:3306/testdb?useUnicode=true&characterEncoding=utf-8&useSSL=false
      driver-class-name: com.mysql.jdbc.Driver
      resource-type: java.sql.Driver
      jta-managed: false
      max-pool-size: 32
      min-idle: 8
    jdbcx.0:
      name: 
      enabled: true
      username: postgres_username
      password: postgres_password
      url: jdbc:postgresql://localhost:5432/otherdb
      driver-class-name: org.postgresql.Driver
      resource-type: java.sql.Driver
      jta-managed: false
      max-pool-size: 32
      min-idle: 8

1.4.2 在SpringBoot应用中配置连接ZooKeeper配置中心获取配置

应用的application.properties如下：

server.bes.spring.boot.config-provider.class=com.bes.enterprise.config.spring.boot.provider.ZooKeeperConfigProvider
spring.cloud.zookeeper.connect-string=localhost:2181,localhost:2182,localhost:2183
spring.cloud.zookeeper.node=/zookeeper/my_application.yml
spring.cloud.zookeeper.file-extension=yml

1.4.3 编写使用从ZooKeeper配置中心获取配置的应用

编写SpingBoot入口类：

package com.example.zookeeper.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ZooKeeperDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(ZooKeeperDemoApplication.class, args);
    }

}

在项目中使用ZooKeeper配置中心的/zookeeper/my_application.yml数据节点装配JDBC连接池：

package com.example.zookeeper.demo;

import org.springframework.stereotype.Service;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;
import java.sql.*;
import java.util.*;
@Service
public class BookService {

    private DataSource myDataSource;

    private DataSource getDataSource() throws SQLException {
        if (myDataSource != null) {
            return myDataSource;
        }

        try {
            InitialContext ctx = new InitialContext();
            DataSource ds = (DataSource) ctx.lookup("myDataSource");
            myDataSource = ds;
            return myDataSource;
        } catch (NamingException nmEx) {
            throw new SQLException("Failure to get datasource", nmEx);
        }
    }

    public void save(Book book) throws SQLException {
        Connection conn = null;
        PreparedStatement pstmt = null;
        try {
            conn = getDataSource().getConnection();
            String sql = "INSERT INTO BOOK(TITLE, AUTHOR, PRICE) VALUES(?,?,?)";
            pstmt = conn.prepareStatement(sql);
            pstmt.setString(1, book.getTitle());
            pstmt.setString(2, book.getAuthor());
            pstmt.setBigDecimal(3, book.getPrice());
            pstmt.execute();
        } finally {
            closeQuietly(pstmt);
            closeQuietly(conn);
        }
    }

    // 省略其余逻辑
}

编译和启动SpringBoot应用，验证是否能从ZooKeeper配置中心获取配置：

mvn clean package
java -jar ./target/bes-lite-zookeeper-demo-1.0.0.jar

输出结果中出现：“Loading configuration from: zookeeper://localhost:2181,localhost:2182,localhost:2183.”则说明成功从ZooKeeper中拉取应用的配置：

2026-02-16T23:00:41.825+08:00  INFO 28780 --- [           main] e.c.s.b.l.RemoteConfigContextInitializer : Loading configuration from: zookeeper://localhost:2181,localhost:2182,localhost:2183.
2026-02-16T23:00:42.216+08:00  INFO 28780 --- [           main] c.e.z.demo.ZooKeeperDemoApplication      : Starting ZooKeeperDemoApplication using Java 21.0.8 with PID 28780
