使用dynamic-datasource-spring-boot-starter自定义数据库密码

大家在使用的时候，只要将例子的设置密码的方法重新编写即可

package com.wins.core.config.mybatis;

import com.baomidou.dynamic.datasource.provider.AbstractJdbcDataSourceProvider;
import com.baomidou.dynamic.datasource.provider.DynamicDataSourceProvider;
import com.baomidou.dynamic.datasource.spring.boot.autoconfigure.DataSourceProperty;
import com.baomidou.dynamic.datasource.spring.boot.autoconfigure.DynamicDataSourceProperties;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.sql.SQLException;
import java.sql.Statement;
import java.util.Map;

@Configuration
public class DataSourceInit {

    private static final Logger log = LoggerFactory.getLogger(DataSourceInit.class);

    @Value("${spring.profiles.active}")
    private String runEnv;

    /**
     * 数据源自定义加载
     *
     * @param properties 数据源配置(某些idea中properties字段可能会爆红,忽略即可,不影响使用 )
     * @return DynamicDataSourceProvider
     */
    @Bean
    public DynamicDataSourceProvider dynamicDataSourceProvider(DynamicDataSourceProperties properties) {
        Map<String, DataSourceProperty> datasourceMap = properties.getDatasource();
        DataSourceProperty masterDataSourceProperty = datasourceMap.get("master");

        String passWord = "";

        // TODO 获取密码，密码解密等操作
        

        masterDataSourceProperty.setPassword(passWord);


        // 加载主数据源(yml中配置的数据源)
        return new AbstractJdbcDataSourceProvider(masterDataSourceProperty.getDriverClassName(),
                masterDataSourceProperty.getUrl(),
                masterDataSourceProperty.getUsername(),
                masterDataSourceProperty.getPassword()) {
            @Override
            protected Map<String, DataSourceProperty> executeStmt(Statement statement) throws SQLException {
                return datasourceMap;
            }
        };
    }
}

 附applicationn-dev数据库模块配置

spring:
  datasource:
    druid:
      stat-view-servlet:
        enabled: true
        loginUsername: root
        loginPassword: abcd1234
        allow:
      web-stat-filter:
        enabled: true
    dynamic:
      druid: # 全局druid参数，绝大部分值和默认保持一致。(现已支持的参数如下,不清楚含义不要乱设置)
        # 连接池的配置信息
        # 初始化大小，最小，最大
        initial-size: 5
        min-idle: 5
        maxActive: 20
        # 配置获取连接等待超时的时间
        maxWait: 60000
        # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
        timeBetweenEvictionRunsMillis: 60000
        # 配置一个连接在池中最小生存的时间，单位是毫秒
        minEvictableIdleTimeMillis: 300000
        validationQuery: SELECT 1 FROM DUAL
        testWhileIdle: true
        testOnBorrow: false
        testOnReturn: false
        # 打开PSCache，并且指定每个连接上PSCache的大小
        poolPreparedStatements: true
        maxPoolPreparedStatementPerConnectionSize: 20
        # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
        filters: stat,wall,slf4j
        # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
        connectionProperties: druid.stat.mergeSql\=true;druid.stat.slowSqlMillis\=5000
      datasource:
        master:
          url: jdbc:mysql://10.102.17.110:3306/wins_home_db_prod?characterEncoding=UTF-8&useUnicode=true&useSSL=false&tinyInt1isBit=false&allowPublicKeyRetrieval=true&serverTimezone=Asia/Shanghai
          username: root
