【spring-boot】如何使用apollo

文章背景

• 本文介绍如果在spring boot中接入apollo
• 官方文档：https://github.com/ctripcorp/apollo/wiki#%E4%B8%80%E6%99%AE%E9%80%9A%E5%BA%94%E7%94%A8%E6%8E%A5%E5%85%A5%E6%8C%87%E5%8D%97

使用官方的apollo

演示环境（Demo）:

• 106.54.227.205
• 账号/密码:apollo/admin

添加配置

spring-boot中如何使用呢

pom.xml中添加配置

        <dependency>
            <groupId>com.ctrip.framework.apollo</groupId>
            <artifactId>apollo-client</artifactId>
            <version>1.1.0</version>
        </dependency>

　配置文件中添加apollo地址

app:
  id: komiles
apollo:
  meta: http://106.54.227.205:8080
  bootstrap:
    enabled: true
    namespaces: application

启动类中添加代码

添加@EnableApolloConfig注解

package com.example.apollodemo;

import com.ctrip.framework.apollo.spring.annotation.EnableApolloConfig;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableApolloConfig
@MapperScan("com.example.apollodemo.mapper")
public class ApolloDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(ApolloDemoApplication.class, args);
        System.out.println("============ apollo demo application end =============");
    }
}

　controller类新增文件

ApolloController.java

package com.example.apollodemo.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author komiles@163.com
 * @date 2020-05-06 17:28
 */
@RestController
@RequestMapping("/apollo")
public class ApolloController {

    @Value("${name}")
    private String name;

    @GetMapping("/name")
    public String name()
    {
        return name;
    }
}

数据库配置如何使用？

同理，generatorConfig.xml中也可以读取数据库配置

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>
    <context id="mysqlTables" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="false"/>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--目标数据库配置-->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                connectionURL="${spring.datasource.url}"
                userId="${spring.datasource.username}"
                password="${spring.datasource.password}" />
        <!-- 指定生成的类型为java类型，避免数据库中number等类型字段 -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!-- 生成model模型，对应的包，存放位置可以指定具体的路径,如/ProjectName/src，也可以使用MAVEN来自动生成 -->
        <javaModelGenerator targetPackage="com.example.apollodemo.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>
            <property name="immutable" value="false"/>
        </javaModelGenerator>
        <!--对应的xml mapper文件  -->

        <sqlMapGenerator targetPackage="mapper"  targetProject="src/main/resources/mybatis">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>
        <!-- 对应的dao接口 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.example.apollodemo.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>
        <!--定义需要操作的表及对应的DTO名称-->
        <table tableName="t_user" domainObjectName="User"/>
    </context>
</generatorConfiguration>
