springboot对数据库密码加密

第一步：maven引jar包

　　　　<dependency>
            <groupId>com.github.ulisesbocchio</groupId>
            <artifactId>jasypt-spring-boot-starter</artifactId>
            <version>1.14</version>
        </dependency>
        <dependency>
            <groupId>com.github.ulisesbocchio</groupId>
            <artifactId>jasypt-spring-boot</artifactId>
            <version>1.14</version>
        </dependency>

第二步：配置文件

#jasypt加密的盐值
jasypt.encryptor.password=erp

第三步：调用加密方法

public class JasyptTest {

    @Autowired
    static StringEncryptor encryptor;
    //加密
    public static void getPass(){
        encryptor = SpringUtil.getBean(StringEncryptor.class);
        String name = encryptor.encrypt("root");
        String password = encryptor.encrypt("firewall_new");
        System.out.println(name); //hifVDwDPW5MNYa0tAabvJQ==
        System.out.println(password);  //5mTXmB5IYPxqiSuD/045cjHEkJz2NhNi
    }
    //解密
    public static void passDecrypt(){
        encryptor = SpringUtil.getBean(StringEncryptor.class);
        String username = encryptor.decrypt("hifVDwDPW5MNYa0tAabvJQ==");
        String password = encryptor.decrypt("5mTXmB5IYPxqiSuD/045cjHEkJz2NhNi");
        System.out.println(username+"--"+password);
    }

}

            for (String active : activeProFiles){

                Resource resource = applicationContext.getResource("classpath:/application-"+active+".properties");

                if(!resource.exists()){
                    String configPath = SpringUtil.getProperty("spring.profiles.path", "");

                    resource = applicationContext.getResource("file:"+configPath+"application-"+active+".properties");
                }
                File file = resource.getFile();
                List<String> lines = FileUtils.readLines(file);
                boolean find = false;
                for (int i = 0; i < lines.size(); i++) {
                    String line = lines.get(i);
                    if(StringUtils.startsWith(line,proName)){
                        line = proName + "="+value;
                        lines.set(i,line);
                        find = true;
                    }

                }
                if( !find ){
                    lines.add(proName+"="+value);
                }
                FileUtils.writeLines(file,lines);

                ContextRefresher bean = getBean(ContextRefresher.class);
                bean.refresh();

            }
        }catch (Exception e){
            e.printStackTrace();
        }

    }
}

 

控制台就会输出加密后的秘钥。

切记：将上面的生成的密匙如下替换，此处主要是数据库密码密文使用ENC进行标识
