SpringBoot项目整合jasypt

1. 依赖引入pom.xml

<!-- jasypt核心依赖 -->
<dependency>
   <groupId>com.github.ulisesbocchio</groupId>
   <artifactId>jasypt-spring-boot-starter</artifactId>
   <version>2.1.1</version> <!-- jasypt2.1.1与spring-boot2.2.6的兼容性是最好的，避免踩坑，泪呀 -->
</dependency>

<!-- jasypt-maven插件，不影响基本功能 -->
<plugin>
  <groupId>com.github.ulisesbocchio</groupId>
  <artifactId>jasypt-maven-plugin</artifactId>
  <version>3.0.3</version>
</plugin>

2. 配置参数application.properties

jasypt.encryptor.password=lE1rl5K$
crypt.user-name=ENC(qvh/QiJYOHNNiJWqhek5Xw==)
crypt.password=ENC(oriTNJoCp5lQ0Tyj5JJmzQ==)
kkk=DEC(123456)

3. 测试代码

package com.yang.ftpdemo.controller;

import lombok.Data;
import org.jasypt.encryption.StringEncryptor;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;

@RestController
@RequestMapping("/crypt")
public class CryptController {

    @Resource
    private StringEncryptor encrypt;

    @Resource
    private CryptConfig cryptConfig;

    @GetMapping("/encrypt")
    public CryptConfig encrypt() {
        String username = encrypt.encrypt("root");
        String password = encrypt.encrypt("root123");

        CryptConfig crypt = new CryptConfig();
        crypt.setPassword(password);
        crypt.setUserName(username);
        return crypt;
    }

    @GetMapping("/decrypt")
    public CryptConfig decrypt() {
        CryptConfig crypt = new CryptConfig();
        BeanUtils.copyProperties(this.cryptConfig, crypt);
        return crypt;
    }
}

@Data
@Configuration
@ConfigurationProperties(prefix = "crypt")
class CryptConfig {
    private String userName;
    private String password;
}

4. 测试
   浏览器访问【http://localhost:8080/crypt/encrypt】得到加密结果，并且每次请求结果不一样：

{
  "userName":"XsWOwhZIag8XBh3DFl4sqA==",
  "password":"3kD2/u+xnM1i5mO2cVMWKw=="
}

浏览器访问【http://localhost:8080/crypt/decrypt】得到解密结果，每次请求结果一样：

{
  "userName":"root",
  "password":"root123"
}

## Maven插件用法不可用，后面补充吧......

 mvn jasypt:encrypt -Djasypt.encryptor.password="myPass"

可能会报如下错误，表示本地环境未安装JDK的JCE模块，它是JDK提供的加密扩展，需要到Oracle官网手动下载，并安装：
