介绍
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。
基础知识
hutool-crypto加密解密工具
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。
request流只能读取一次的问题
问题描述
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。
解决办法
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。
下面这样就实现了流的重复获取:
工具类(InpjavascriptutStreamHttpServletRequestWrapper):package com.mry.springboottools.validation; import org.apache.commons.io.IOUtils; import javax.servlet.ReadListener; import javax.servlet.ServletInputStream; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletRequestWrapper; 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(); } } }
Filter过滤器(HttpServletRequestInputStreamFilter):
package com.mry.springboottools.validation; import org.springframework.core.annotation.Order; import org.springframework.stereotype.Component; import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import java.io.IOException; import static org.springframework.core.Ordered.HIGHEST_PRECEDENCE; /** * @author * @description: 请求流转换为多次读取的请求流 过滤器 */ @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); } }
SpringBoot的参数校验validation
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。
package com.mry.springboottools.validation; import javax.validation.ConstraintViolation; import javax.validation.Validation; import javax.validation.Validator; import java.util.LinkedList; import java.util.List; import java.util.Set; /** * @author * @description 验证工具类 */ public class ValidationUtils { private static final Validator VALIDATOR = Validation.buildDefaultValidatorFactory().getValidator(); /** * 验证数据 * @param object 数据 */ public static void validate(Object object) throws CustomizeException { Set<ConstraintViolation<Object>> validate = VALIDATOR.validate(object); // 验证结果异常 throwparamException(validate); } /** * 验证数据(分组) * @param object 数据 * @param groups 所在组 */ public static void validate(Object object, Class<?> ... groups) throws CZAqRMUCustomizeException { Set<ConstraintViolation<Object>&gCZAqRMUt; validate = VALIDATOR.validate(object, groups); // 验证结果异常 throwParamException(validate); } /** * 验证数据中的某个字段(分组) * @param object 数据 * @param propertyName 字段名称 */ public static void validate(Object object, String propertyName) throws CustomizeException { Set<ConstraintViolation<Object>> validate = VALIDATOR.validateProperty(object, propertyName); // 验证结果异常 throwParamException(validate); } /** * 验证数据中的某个字段(分组) * @param object 数据 * @param propertyName 字段名称 * @param groups 所在组 */ public static void validate(Object object, String propertyName, Class<?> ... groups) throws CustomizeException { Set<ConstraintViolation<Object>> validate = VALIDATOR.validateProperty(object, propertyName, groups); // 验证结果异常 throwParamException(validate); } /** * 验证结果异常 * @param validate 验证结果 */ private static void throwParamException(Set<ConstraintViolation<Object>> validate) throws CustomizeException { if (validate.size() > 0) { List<String> fieldList = new LinkedList<>(); List<String> msgList = new LinkedList<>(); for (ConstraintViolation<Object> next : validate) { fieldList.add(next.getPropertyPath().toString()); msgList.add(next.getMessage()); } throw new ParamException(fieldList, msgList); } } }
自定义参数异常:
package com.mry.springboottools.validation; import lombok.Getter; import org.springframework.util.CollectionUtils; import java.util.List; /** * @author * @description 自定义参数异常 */ @Getter public class ParamException extends CustomizeException { private List<String> fieldList; private List<String> msgList; public ParamException(String message) { super(message); } public ParamException(String message, Throwable cause) { super(message, cause); } public ParamException(List<String> fieldList, List<String> msgList) throws CustomizeException { super(generatorMessage(fieldList, msgList)); this.fieldList = fieldList; this.msgList = msgList; } public ParamException(List<String> fieldList, List<String> msgList, Exception ex) throws CustomizeException { super(generatorMessage(fieldList, msgList), ex); this.fieldList = fieldList; this.msgList = msgList; } private static String generatorMessage(List<String> fieldList, List<String> msgList) throws CustomizeException { if (CollectionUtils.isEmpty(fieldList) || CollectionUtils.isEmpty(msgList) || fieldList.size() != msgList.size()) { return "参数错误"; } StringBuilder message = new StringBuilder(); for (int i = 0; i < fieldList.size(); i++) { String field = fieldList.get(i); String msg = msgList.get(i); if (i == fieldList.size() - 1) { message.append(field).append(":").append(msg); } else { message.append(field).append(":").append(msg).append(","); } } return message.toString(); } }
自定义异常:
package com.mry.springboottools.validation; /** * @author * @description: 自定义异常 */ public class CustomizeException extends Exception { public CustomizeException(String message, Throwable cause) { super(message, cause); } public CustomizeException(String message) { super(message); } }
自定义starter
自定义starter步骤:
1.创建工厂,编写功能代码;2.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;3.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和ResponseBodyAdvice
1.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;
2.ResponseBodyAdvice是对请求响应的json传进行处理,一般用于相应结果的加密;功能介绍
接口数据的时候,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,加密的会自动解密,取得对应的数据。
功能细节
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。
功能提供Springboot的starter,实现开箱即用。
