网上有好多通过aop切面以及自定义的RSA工具类进行加密解密的方法，期中的过程繁琐也不好用，博主研究了一天从网上到了超好用的基于Springboot框架实现的接口RSA加密解密方式，通过rsa-encrypt-body-spring-boot实现了对Spring Boot接口返回值、参数值通过注解的方式自动加解密。注意：rsa-encrypt-body-spring-boot是某一个大神写的工具类上传到了maven库中，大家引用即可
一、引入rsa-encrypt-body-spring-boot
<dependency>
<groupid>cn.shuibo</groupid>
<artifactid>rsa-encrypt-body-spring-boot</artifactid>
<version>1.0.1.RELEASE</version>
</dependency>二、启动类Application中添加@EnableSecurity注解
@SpringBootApplication
@EnableCaching
@MapperScan("com.ujia")
@EnableScheduling
@EnableSecurity
public class RestApplication {
public static void main(String[] args) {
SpringApplication.run(RestApplication.class, args);
}
}三、在application.yml或者application.properties中添加RSA公钥及私钥
rsa:
encrypt:
open: true # 是否开启加密 true or false
showLog: true # 是否打印加解密log true or false
publicKey: # RSA公钥
privateKey: # RSA私钥补充知识：rsa公钥私钥生成命令，在电脑文件夹中打开命令框依次执行
openssl
# 生成私钥
genrsa -out id_rsa_private 2048
# 生成私钥(把RSA私钥转换成PKCS8格式)
pkcs8 -topk8 -inform PEM -in id_rsa_private -outform pem -nocrypt -out id_rsa_private_pkcs
# 生成公钥
rsa -in id_rsa_private -pubout -out id_rsa_public.pub
重点注意：生成的私钥一定要转成pkcs8，否则会报错

@Encrypt
@GetMapping("/encryption")
public TestBean encryption(){
TestBean testBean = new TestBean();
testBean.setName("shuibo.cn");
testBean.setAge(18);
return testBean;
}五、对参数进行解密
@Decrypt
@PostMapping("/decryption")
public String Decryption(@RequestBody TestBean testBean){
return testBean.toString();
}返回结果加密——运行结果：
