springboot 使用druid 配置数据库密码加密

springboot 使用druid 配置数据库密码加密
1.添加DruidConfig配置类

package org.jeecg.config;import com.alibaba.druid.filter.config.ConfigTools;
import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import javax.sql.DataSource;
import java.sql.SQLException;/*** Druid配置类* 1、可以监控数据库访问性能，内置了插件：StatFilter，能够详细统计SQL执行性能，用于线上分析数据库访问性能。* 2、替换DBCP、C3P0数据库连接池，提供了一个高效稳定的扩展性能好的数据库连接池DruidDataSource。* 3、数据库加密，DruidDriuiver和DruidDataSource都支持PasswordCallback。* 4、SQL执行日志。* 5、扩展JDBC，如果你要对JDBC层有编程的需求，可以通过Druid提供的Filter-Chain机制，很方便编写JDBC层的扩展插件* Druid是一个阿里开源的数据库连接池框架，有可视化界面。* http://localhost:8080/druid/login.html* 可以查看sql访问速度等等很多信息，感觉还是比较有用的。集成进来试试* @author maybe*/
@Configuration
@Slf4j
public class DruidConfig {//使用@value注入配置文件中信息@Value("${spring.datasource.dynamic.datasource.master.url}")private String dbUrl;@Value("${spring.datasource.dynamic.datasource.master.username}")private String username;@Value("${spring.datasource.dynamic.datasource.master.password}")private String password;@Value("${spring.datasource.dynamic.datasource.master.public-key}")private String publicKey;@Value("${spring.datasource.dynamic.datasource.master.driver-class-name}")private String driverClassName;@Value("${spring.datasource.dynamic.druid.initial-size}")private int initialSize;@Value("${spring.datasource.dynamic.druid.min-idle}")private int minIdle;@Value("${spring.datasource.dynamic.druid.max-active}")private int maxActive;@Value("${spring.datasource.dynamic.druid.max-wait}")private int maxWait;@Value("${spring.datasource.dynamic.druid.timeBetweenEvictionRunsMillis}")private int timeBetweenEvictionRunsMillis;@Value("${spring.datasource.dynamic.druid.minEvictableIdleTimeMillis}")private int minEvictableIdleTimeMillis;@Value("${spring.datasource.dynamic.druid.validationQuery}")private String validationQuery;@Value("${spring.datasource.dynamic.druid.testWhileIdle}")private boolean testWhileIdle;@Value("${spring.datasource.dynamic.druid.testOnBorrow}")private boolean testOnBorrow;@Value("${spring.datasource.dynamic.druid.testOnReturn}")private boolean testOnReturn;@Value("${spring.datasource.dynamic.druid.filters}")private String filters;@Value("${spring.datasource.dynamic.druid.logSlowSql}")private String logSlowSql;@Value("${spring.datasource.dynamic.druid.connectionProperties}")private String connectionProperties;@Beanpublic ServletRegistrationBean druidServlet() throws Exception {ServletRegistrationBean reg = new ServletRegistrationBean();reg.setServlet(new StatViewServlet());reg.addUrlMappings("/druid/*");//配置访问URLreg.addInitParameter("loginUsername", username);  //配置用户名，这里使用数据库账号。reg.addInitParameter("loginPassword", ConfigTools.decrypt(publicKey,password));  //配置用户名，这里使用数据库密码reg.addInitParameter("logSlowSql", logSlowSql);   //是否启用慢sqlreturn reg;}@Beanpublic FilterRegistrationBean filterRegistrationBean() {FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();filterRegistrationBean.setFilter(new WebStatFilter());filterRegistrationBean.addUrlPatterns("/*");filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");  //配置那些资源不被拦截filterRegistrationBean.addInitParameter("profileEnable", "true");return filterRegistrationBean;}/*** 这个应该是数据库连接池配置* @return* @throws Exception*/@Beanpublic DataSource druidDataSource() throws Exception {DruidDataSource datasource = new DruidDataSource();datasource.setUrl(dbUrl);datasource.setUsername(username);datasource.setPassword(ConfigTools.decrypt(publicKey,password));datasource.setDriverClassName(driverClassName);datasource.setInitialSize(initialSize);datasource.setMinIdle(minIdle);datasource.setMaxActive(maxActive);datasource.setMaxWait(maxWait);datasource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);datasource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);datasource.setValidationQuery(validationQuery);datasource.setTestWhileIdle(testWhileIdle);datasource.setTestOnBorrow(testOnBorrow);datasource.setTestOnReturn(testOnReturn);datasource.setConnectionProperties(connectionProperties);try {datasource.setFilters(filters);} catch (SQLException e) {log.error("druid configuration initialization filter:{}",e);}return datasource;}}

2.给配置文件中配置数据库

springdatasource:druid:stat-view-servlet:enabled: trueloginUsername: adminloginPassword: 123456allow:web-stat-filter:enabled: truedynamic: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: 5min-idle: 5maxActive: 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: 300000validationQuery: SELECT 1 FROM DUALtestWhileIdle: truetestOnBorrow: falsetestOnReturn: falselogSlowSql: true# 打开PSCache，并且指定每个连接上PSCache的大小poolPreparedStatements: truemaxPoolPreparedStatementPerConnectionSize: 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,config# 通过connectProperties属性来打开mergeSql功能；慢SQL记录connectionProperties: druid.stat.mergeSql\=true;druid.stat.slowSqlMillis\=5000datasource:master:url: jdbc:mysql://127.0.0.1:3306/jeecg_boot?characterEncoding=UTF-8&useUnicode=true&useSSL=falseusername: rootpassword: U9FSu3rAgada8zV0VGTVEeAKc3Ccxgzbz9nuC4AWKzrxdZIJLvdnCjy9D913jI5sHxlzK6HfdR5+cEbPhM8v9A==public-key: MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBALR6ubZQXlaJQIVTxgqxKMdhKjhwTcsQDQq8Rvxa0G/gnZHCMxSZMtiWD8p7L4pHYWys99sOzfIBiP14LZkzNMUCAwEAAQ==driver-class-name: com.mysql.jdbc.Driver# 多数据源配置#multi-datasource1:#url: jdbc:mysql://localhost:3306/jeecg-boot2?useUnicode=true&characterEncoding=utf8&autoReconnect=true&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true#username: root#password: root#driver-class-name: com.mysql.jdbc.Driver

那么现在spring boot集成druid已经完成了。只差将密码加密并且写入配置文件即可。

druid进行数据库密码加密：
1，找到druid的相关jar包
这里我是用的是

2，进行加密
进行cmd找到该jar包所在目录，执行：

java -cp druid-1.1.17.jar com.alibaba.druid.filter.config.ConfigTools your-password
得到：

privateKey:MIIBVQIBADANBgkqhkiG9w0BAQEFAASCAT8wggE7AgEAAkEAtHq5tlBeVolAhVPGCrEox

fdR5+cEbPhM8v9A==

1，privateKey  私钥，进行加密时的key2，publickey  公钥，进行解密时的key3，password  加密后的密码 

将password和publickey填入配置文件中即可完成。
