在我们日常的Java开发中,免不了和其他系统的业务交互,或者微服务之间的接口调用
如果我们想保证数据传输的安全,对接口出参加密,入参解密。
但是不想写重复代码,我们可以提供一个通用starter,提供通用加密解密功能
hutool-crypto提供了很多加密解密工具,包括对称加密,非对称加密,摘要加密等等,这不做详细介绍。
在接口调用链中,request的请求流只能调用一次,处理之后,如果之后还需要用到请求流获取数据,就会发现数据为空。
比如使用了filter或者aop在接口处理之前,获取了request中的数据,对参数进行了校验,那么之后就不能在获取request请求流了
继承HttpServletRequestWrapper
,将请求中的流copy一份,复写getInputStream
和getReader方法供外部使用。每次调用后的getInputStream
方法都是从复制出来的二进制数组中进行获取,这个二进制数组在对象存在期间一致存在。
使用Filter过滤器,在一开始,替换request为自己定义的可以多次读取流的request。
这样就实现了流的重复获取
InputStreamHttpServletRequestWrapper
- package xyz.hlh.cryptotest.utils;

- import javax.servlet.ServletInputStream;

- import java.io.BufferedReader;
- import java.io.ByteArrayInputStream;
- import java.io.ByteArrayOutputStream;
- import java.io.IOException;
- import java.io.InputStreamReader;
-
- /**
- * 请求流支持多次获取
- */
- public class InputStreamHttpServletRequestWrapper extends HttpServletRequestWrapper {
-
- /**
- * 用于缓存输入流
- */
- private ByteArrayOutputStream cachedBytes;
-
- public InputStreamHttpServletRequestWrapper(HttpServletRequest request) {
- super(request);
- }
-
- @Override
- public ServletInputStream getInputStream() throws IOException {
- if (cachedBytes == null) {
- // 首次获取流时,将流放入 缓存输入流 中
- cacheInputStream();
- }
-
- // 从 缓存输入流 中获取流并返回
- return new CachedServletInputStream(cachedBytes.toByteArray());
- }
-
- @Override
- public BufferedReader getReader() throws IOException {
- return new BufferedReader(new InputStreamReader(getInputStream()));
- }
-
- /**
- * 首次获取流时,将流放入 缓存输入流 中
- */
- private void cacheInputStream() throws IOException {
- // 缓存输入流以便多次读取。为了方便, 我使用 org.apache.commons IOUtils
- cachedBytes = new ByteArrayOutputStream();
- IOUtils.copy(super.getInputStream(), cachedBytes);
- }
-
- /**
- * 读取缓存的请求正文的输入流
- * <p>
- * 用于根据 缓存输入流 创建一个可返回的
- */
- public static class CachedServletInputStream extends ServletInputStream {
-
- private final ByteArrayInputStream input;
-
- public CachedServletInputStream(byte[] buf) {
- // 从缓存的请求正文创建一个新的输入流
- input = new ByteArrayInputStream(buf);
- }
-
- @Override
- public boolean isFinished() {
- return false;
- }
-
- @Override
- public boolean isReady() {
- return false;
- }
-
- @Override
- public void setReadListener(ReadListener listener) {
-
- }
-
- @Override
- public int read() throws IOException {
- return input.read();
- }
- }
-
- }
HttpServletRequestInputStreamFilter

- @Component
- @Order(HIGHEST_PRECEDENCE + 1) // 优先级最高
- public class HttpServletRequestInputStreamFilter implements Filter {
-
- @Override
- public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
-
- // 转换为可以多次获取流的request
- HttpServletRequest httpServletRequest = (HttpServletRequest) request;
- InputStreamHttpServletRequestWrapper inputStreamHttpServletRequestWrapper = new InputStreamHttpServletRequestWrapper(httpServletRequest);
-
- // 放行
- chain.doFilter(inputStreamHttpServletRequestWrapper, response);
- }
- }
为了减少接口中,业务代码之前的大量冗余的参数校验代码
SpringBoot-validation
提供了优雅的参数校验,入参都是实体类,在实体类字段上加上对应注解,就可以在进入方法之前,进行参数校验,如果参数错误,会抛出错误BindException
,是不会进入方法的。
这种方法,必须要求在接口参数上加注解@Validated
或者是@Valid
但是很多清空下,我们希望在代码中调用某个实体类的校验功能,所以需要如下工具类
ParamException
- package xyz.hlh.cryptotest.exception;
-
- import lombok.Getter;
-
- import java.util.List;
-
- /**

自定义starter步骤
创建工厂,编写功能代码
声明自动配置类,把需要对外提供的对象创建好,通过配置类统一向外暴露
在resource目录下准备一个名为spring/spring.factories
的文件,以org.springframework.boot.autoconfigure.EnableAutoConfiguration
为key,自动配置类为value列表,进行注册
RequestBodyAdvice
是对请求的json串进行处理, 一般使用环境是处理接口参数的自动解密
ResponseBodyAdvice
是对请求相应的jsoin传进行处理,一般用于相应结果的加密
接口相应数据的时候,返回的是加密之后的数据 接口入参的时候,接收的是解密之后的数据,但是在进入接口之前,会自动解密,取得对应的数据
加密解密使用对称加密的AES算法,使用hutool-crypto模块进行实现
所有的实体类提取一个公共父类,包含属性时间戳,用于加密数据返回之后的实效性,如果超过60分钟,那么其他接口将不进行处理。
如果接口加了加密注解EncryptionAnnotation
,并且返回统一的json数据Result类,则自动对数据进行加密。如果是继承了统一父类RequestBase
的数据,自动注入时间戳,确保数据的时效性
如果接口加了解密注解DecryptionAnnotation
,并且参数使用RequestBody注解标注,传入json使用统一格式RequestData类,并且内容是继承了包含时间长的父类RequestBase
,则自动解密,并且转为对应的数据类型
