1.xml配置数据库连接配置
#数据源配置
spring.datasource.username=beebotlark
spring.datasource.password=WDShxRWTLSuKM6ucPN4E8hi0YWglium26wJVKitxRpzN2sopztgZpvgi4YFnuPXrAiLPMjuzgYK13we5SEwIHQ==spring.datasource.url=localhost:3306/local?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.is-init=false
spring.datasource.init_file_name=DML,DDL
#公钥
spring.datasource.public-key=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAN/HfAEsiZ/uXs3/wKTa6BSUr/6QF/sAcHIoHMO56TFiNDPXpnwtsUC5JJDu1rq9kxU0Ilc0CVEYZ5g5aD23ZVkCAwEAAQ==
#配置解密
spring.datasource.druid.filters=config
spring.datasource.druid.connection-properties=config.decrypt=true;config.decrypt.key=${spring.datasource.public-key}
2.创建DruidConfig配置类
@Configuration
public class DruidConfig{
}
3.注入配置文件中的数据库配置
/**
* datasourceUrl 连接数据库url
*/
@Value("${spring.datasource.url}")
private String datasourceUrl;
/**
* driverClassName 数据库驱动
*/
@Value("${spring.datasource.driver-class-name}")
private String driverClassName;
/**
* datasourceUserName 连接数据库的用户名
*/
@Value("${spring.datasource.username}")
private String datasourceUserName;
/**
* databasePassword 连接数据库密码
*/
@Value("${spring.datasource.password}")
private String databasePassword;
/**
* 注入数据库公钥
*/
@Value("${spring.datasource.public-key}")
private String datasourcePublicKey;
4.调用druid公钥+密码钥进行解密,并执行创建数据库语句
/**
* @return dataSource
* @description 配置数据库自动创建
* 如果连接地址没有对应的数据库则创建,前提是有root账号,或者是非root账号具有建库的权限
*/
@Bean
public DataSource dataSourceConfig() {
DruidDataSource dataSource = new DruidDataSource();
String decrypt = null;
//druid解密
try {
decrypt = ConfigTools.decrypt(datasourcePublicKey, databasePassword);
} catch (Exception e) {
log.error("公钥解密异常:{}", e.getMessage());
}
dataSource.setUrl(datasourceUrl);
dataSource.setUsername(datasourceUserName);
//将解密后的密码添加到datasource源
dataSource.setPassword(decrypt);
dataSource.setDriverClassName(driverClassName);
Connection connection = null;
PreparedStatement state = null;
try {
Class.forName(driverClassName);
// 截取数据库问问好前的连接参数
String sqlUrl = datasourceUrl.substring(0, datasourceUrl.indexOf("?"));
// 获取连接数据库的url
String databasesUrl = sqlUrl.substring(0, sqlUrl.lastIndexOf("/"));
// 截取数据库名
String databaseName = sqlUrl.substring(sqlUrl.lastIndexOf("/") + 1);
// 创建连接
connection = DriverManager.getConnection(databasesUrl, datasourceUserName, decrypt);
// 创建传输通道,并设置占位符
String sql = "create database if not exists ? default character set utf8 COLLATE utf8_general_ci";
state = connection.prepareStatement(sql);
// 将数据库名注入到占位符
state.setString(1, databaseName);
// 获取到注入的sql语句
String resultSql = ((ClientPreparedStatement) state).asSql();
String executeSql = resultSql.replaceAll("\'", "`");
int execute = state.executeUpdate(executeSql);
log.info("sql语句执行状态:{}", execute);
} catch (Throwable e) {
log.error("数据库连接异常:{}", e.getMessage());
} finally {
try {
if (null != state) {
state.close();
}
if (null != connection) {
connection.close();
}
} catch (SQLException throwable) {
log.error("sql语句异常:{}", throwable.getMessage());
}
}
return dataSource;
}
