springMVC，springboot整合jasypt

生成加密串 
public class Encryptor {
    public static void main(String[] args) {
        BasicTextEncryptor textEncryptor = new BasicTextEncryptor();
        textEncryptor.setPassword("mysalt");//自定义加密盐
        String myEncryptedPassword = textEncryptor.encrypt("jdbcpasword");
        System.out.println("Encrypted DB password: " + myEncryptedPassword );
    }
}

jdbc连接数据库密码设置为加密的使用ENC(）

password: ENC(myEncryptedPassword )

一、.springMvc

1.引入包

<dependency>
    <groupId>org.jasypt</groupId>
    <artifactId>jasypt-spring4</artifactId>
    <version>1.9.2</version>
</dependency>

2.创建一个自定义DataSource 项目使用什么JDBC组件按自己项目进行修改，我的项目是Druid JDBC组件所以继承了Druid

public class CustomDruidDataSource extends DruidDataSource {

    Pattern pattern = Pattern.compile("^ENC\\((.+)\\)$");

    // 创建一个 Jasypt 加密器实例
    StandardPBEStringEncryptor encryptor;

    public CustomDruidDataSource() {
        super();
        encryptor = new StandardPBEStringEncryptor();
        String password = System.getProperty("jasypt.encryptor.password");
        if (StringUtils.isNotBlank(password)) {
            encryptor.setPassword(password);
        }
    }

    @Override
    public void setUsername(String username) {
        String realUserName = username;
        Matcher matcher = pattern.matcher(username);
        if (matcher.matches()) {
            String encryptedUsername = matcher.group(1);
            realUserName = encryptor.decrypt(encryptedUsername);
        }
        super.setUsername(realUserName);
    }

    @Override
    public void setPassword(String password) {
        String realPassword = password;
        Matcher matcher = pattern.matcher(password);
        if (matcher.matches()) {
            String encryptedPassword = matcher.group(1);
            realPassword = encryptor.decrypt(encryptedPassword);
        }
        super.setPassword(realPassword);
    }
}

3.applicationContext.xml修改配置修改数据库配置的数据源为自定义的DataSource

<bean id="dataSource" class="com.*.*.config.CustomDruidDataSource" init-method="init" destroy-method="close">
    <!-- 基本属性 url、user、password -->
    <property name="url" value="${jdbc_url}" />
    <property name="username" value="${jdbc_user}" />
    <property name="password" value="${jdbc_password}" />
</bean>

4.启动命令增加VM参数

4.1本地tomcat VM参数增加 

-Djasypt.encryptor.password=mysalt

4.2服务器TOMCAT 修改

tomcat/bin/catalina.sh
JAVA_OPTS="$JAVA_OPTS -Djasypt.encryptor.password=mysalt"

二、springboot

1.引入包
<dependency>
    <groupId>com.github.ulisesbocchio</groupId>
    <artifactId>jasypt-spring-boot-starter</artifactId>
    <version>2.1.2</version>
</dependency>

2.启动命令增加

-Djasypt.encryptor.password=mysalt//自定义加密盐
