SpringBoot项目整合jasypt实现过程详解

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>

配置参数application.properties

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

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;
}

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：
