基礎知識
hutool-crypto加密解密工具
hutool-crypto提供了很多加密解密工具,包括對稱加密,非對稱加密,摘要加密等等,這不做詳細介紹。
request流只能讀取一次的問題
問題描述
在接口調(diào)用鏈中,request的請求流只能調(diào)用一次,處理之后,如果之后還需要用到請求流獲取數(shù)據(jù),就會發(fā)現(xiàn)數(shù)據(jù)為空。
比如使用了filter或者aop在接口處理之前,獲取了request中的數(shù)據(jù),對參數(shù)進行了校驗,那么之后就不能在獲取request請求流了。
解決辦法
繼承HttpServletRequestWrapper,將請求中的流copy一份,復寫getInputStream和getReader方法供外部使用。每次調(diào)用后的getInputStream方法都是從復制出來的二進制數(shù)組中進行獲取,這個二進制數(shù)組在對象存在期間一致存在。
使用Filter過濾器,在一開始,替換request為自己定義的可以多次讀取流的request。
下面這樣就實現(xiàn)了流的重復獲取:
工具類(InputStreamHttpServletRequestWrapper):
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; /** * 請求流支持多次獲取 */ public class InputStreamHttpServletRequestWrapper extends HttpServletRequestWrapper { /** * 用于緩存輸入流 */ private ByteArrayOutputStream cachedBytes; public InputStreamHttpServletRequestWrapper(HttpServletRequest request) { super(request); } @Override public ServletInputStream getInputStream() throws IOException { if (cachedBytes == null) { // 首次獲取流時,將流放入 緩存輸入流 中 cacheInputStream(); } // 從 緩存輸入流 中獲取流并返回 return new CachedServletInputStream(cachedBytes.toByteArray()); } @Override public BufferedReader getReader() throws IOException { return new BufferedReader(new InputStreamReader(getInputStream())); } /** * 首次獲取流時,將流放入 緩存輸入流 中 */ private void cacheInputStream() throws IOException { // 緩存輸入流以便多次讀取。為了方便, 我使用 org.apache.commons IOUtils cachedBytes = new ByteArrayOutputStream(); IOUtils.copy(super.getInputStream(), cachedBytes); } /** * 讀取緩存的請求正文的輸入流 * <p> * 用于根據(jù) 緩存輸入流 創(chuàng)建一個可返回的 */ public static class CachedServletInputStream extends ServletInputStream { private final ByteArrayInputStream input; public CachedServletInputStream(byte[] buf) { // 從緩存的請求正文創(chuàng)建一個新的輸入流 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過濾器(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: 請求流轉換為多次讀取的請求流 過濾器 */ @Component @Order(HIGHEST_PRECEDENCE + 1) // 優(yōu)先級最高 public class HttpServletRequestInputStreamFilter implements Filter { @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { // 轉換為可以多次獲取流的request HttpServletRequest httpServletRequest = (HttpServletRequest) request; InputStreamHttpServletRequestWrapper inputStreamHttpServletRequestWrapper = new InputStreamHttpServletRequestWrapper(httpServletRequest); // 放行 chain.doFilter(inputStreamHttpServletRequestWrapper, response); } }
SpringBoot的參數(shù)校驗validation
為了減少接口中,業(yè)務代碼之前的大量冗余的參數(shù)校驗代碼
SpringBoot-validation提供了優(yōu)雅的參數(shù)校驗,入?yún)⒍际菍嶓w類,在實體類字段上加上對應注解,就可以在進入方法之前,進行參數(shù)校驗,如果參數(shù)錯誤,會拋出錯誤BindException,是不會進入方法的。
這種方法,必須要求在接口參數(shù)上加注解@Validated或者是@Valid
但是很多清空下,我們希望在代碼中調(diào)用某個實體類的校驗功能,所以需要如下工具類。
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 驗證工具類 */ public class ValidationUtils { private static final Validator VALIDATOR = Validation.buildDefaultValidatorFactory().getValidator(); /** * 驗證數(shù)據(jù) * @param object 數(shù)據(jù) */ public static void validate(Object object) throws CustomizeException { Set<ConstraintViolation<Object>> validate = VALIDATOR.validate(object); // 驗證結果異常 throwParamException(validate); } /** * 驗證數(shù)據(jù)(分組) * @param object 數(shù)據(jù) * @param groups 所在組 */ public static void validate(Object object, Class<?> ... groups) throws CustomizeException { Set<ConstraintViolation<Object>> validate = VALIDATOR.validate(object, groups); // 驗證結果異常 throwParamException(validate); } /** * 驗證數(shù)據(jù)中的某個字段(分組) * @param object 數(shù)據(jù) * @param propertyName 字段名稱 */ public static void validate(Object object, String propertyName) throws CustomizeException { Set<ConstraintViolation<Object>> validate = VALIDATOR.validateProperty(object, propertyName); // 驗證結果異常 throwParamException(validate); } /** * 驗證數(shù)據(jù)中的某個字段(分組) * @param object 數(shù)據(jù) * @param propertyName 字段名稱 * @param groups 所在組 */ public static void validate(Object object, String propertyName, Class<?> ... groups) throws CustomizeException { Set<ConstraintViolation<Object>> validate = VALIDATOR.validateProperty(object, propertyName, groups); // 驗證結果異常 throwParamException(validate); } /** * 驗證結果異常 * @param validate 驗證結果 */ 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); } } }
自定義參數(shù)異常:
package com.mry.springboottools.validation; import lombok.Getter; import org.springframework.util.CollectionUtils; import java.util.List; /** * @author * @description 自定義參數(shù)異常 */ @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 "參數(shù)錯誤"; } 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(); } }
自定義異常:
package com.mry.springboottools.validation; /** * @author * @description: 自定義異常 */ public class CustomizeException extends Exception { public CustomizeException(String message, Throwable cause) { super(message, cause); } public CustomizeException(String message) { super(message); } }
自定義starter
自定義starter步驟:
1.創(chuàng)建工廠,編寫功能代碼;
2.聲明自動配置類,把需要對外提供的對象創(chuàng)建好,通過配置類統(tǒng)一向外暴露;
3.在resource目錄下準備一個名為spring/spring.factories的文件,以org.springframework.boot.autoconfigure.EnableAutoConfiguration為key,自動配置類為value列表,進行注冊;
RequestBodyAdvice和ResponseBodyAdvice
1.RequestBodyAdvice是對請求的json串進行處理, 一般使用環(huán)境是處理接口參數(shù)的自動解密;
2.ResponseBodyAdvice是對請求響應的json傳進行處理,一般用于相應結果的加密;
功能介紹
接口數(shù)據(jù)的時候,返回的是加密之后的數(shù)據(jù) 接口入?yún)⒌臅r候,接收的是解密之后的數(shù)據(jù),但是在進入接口之前,加密的會自動解密,取得對應的數(shù)據(jù)。
功能細節(jié)
加密解密使用對稱加密的AES算法,使用hutool-crypto模塊進行實現(xiàn)
所有的實體類提取一個公共父類,包含屬性時間戳,用于加密數(shù)據(jù)返回之后的實效性,如果超過60分鐘,那么其他接口將不進行處理。
如果接口加了加密注解EncryptionAnnotation,并且返回統(tǒng)一的json數(shù)據(jù)Result類,則自動對數(shù)據(jù)進行加密。如果是繼承了統(tǒng)一父類RequestBase的數(shù)據(jù),自動注入時間戳,確保數(shù)據(jù)的時效性。
如果接口加了解密注解DecryptionAnnotation,并且參數(shù)使用RequestBody注解標注,傳入json使用統(tǒng)一格式RequestData類,并且內(nèi)容是繼承了包含時間長的父類RequestBase,則自動解密,并且轉為對應的數(shù)據(jù)類型。
功能提供Springboot的starter,實現(xiàn)開箱即用。
