Springboot apollo原理及使用方法详解

文章背景

如果在spring boot中接入apollo官方文档：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

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 [e-mail]
 * @date 2020-05-06 17:28
 */
@restcontroller
@requestmapping("/apollo")
public class apollocontroller {
 
  @value("${name}")
  private string name;
 
  @getmapping("/name")
  public string name()
  {
    return name;
  }
}

可以读取到配置为kongming.

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>
