Spring配置类-获取配置类加密数据库连接

对数据库连接信息加解密，配置信息为密文设置在nacos配置中心，spring.prop.key为密钥，加解密使用

配置密文信息可有由密钥key依据加解密方法获得

@Configuration
public class DataSourceConfig {
    @Bean(name = "myDataSource")
    public DataSource dataSource(Environment environment) {

        HikariDataSource dataSource = new HikariDataSource();
        String key = environment.getProperty("spring.prop.key");
        String url = environment.getProperty("spring.datasource.url");
        String userName = environment.getProperty("spring.datasource.username");
        String passdd = environment.getProperty("spring.datasource.password");

        dataSource.setJdbcUrl(SM4Utils.decryptCbc(StringUtils.stringToHexString(key), url));
        dataSource.setUsername(SM4Utils.decryptCbc(StringUtils.stringToHexString(key), userName));
        dataSource.setPassword(SM4Utils.decryptCbc(StringUtils.stringToHexString(key), passdd));
        dataSource.setDriverClassName(environment.getProperty("spring.datasource.driver-class-name"));
        return dataSource;
    }
