SpringBoot入门建站全系列(三十三)集成validator校验接口数据
SpringBoot入门建站全系列(三十三)集成validator校验接口数据
一、概述
在开发中经常需要写一些字段校验的代码,比如字段非空,字段长度限制,邮箱格式验证等等,如果我们直接将这些校验写死在代码里,将会遇到这种现象: 1. 验证代码繁琐,重复劳动 2. 方法内代码显得冗长 3. 代码可读性不高
所以,我们可以使用hibernate validator来对字段的校验工作统一完成。
spring-boot-starter-web中默认引入了hibernate-validator,因此,在SpringBoot项目中,我们可以直接使用hibernate-validator的特性。
这一篇篇文章本应该放在SpringBoot入门建站全系列的前面章节讲述,这里权做对该系列的补充了。

二、基础知识
首先,基础知识是必须要了解的,我这里整理了下最新的注解,比网上一下子搜到的博客更全面。
validator的功能是由hibernate-validator提供的,所以在Spring官方文档里是找不到关于它的说明的,需要到hibernate-validator官网查看: https:// docs.jboss.org/hibernat e/stable/validator/reference/en-US/html_single/#section-builtin-constraints

import java.util.Date; import java.util.List; import javax.validation.constraints.AssertFalse; import javax.validation.constraints.AssertTrue; import javax.validation.constraints.Digits; import javax.validation.constraints.Email; import javax.validation.constraints.Future; import javax.validation.constraints.Max; import javax.validation.constraints.Min; import javax.validation.constraints.Negative; import javax.validation.constraints.NotBlank; import javax.validation.constraints.NotEmpty; import javax.validation.constraints.NotNull; import javax.validation.constraints.Null; import javax.validation.constraints.Past; import javax.validation.constraints.Pattern; import javax.validation.constraints.Positive; import javax.validation.constraints.Size; import org.hibernate.validator.constraints.Length; import org.hibernate.validator.constraints.Range; import org.hibernate.validator.constraints.URL; import com.fasterxml.jackson.annotation.JsonFormat; import lombok.AllArgsConstructor; import lombok.Builder; import lombok.Data; import lombok.NoArgsConstructor; @Data @NoArgsConstructor @AllArgsConstructor @Builder public class UserInfo { @Null(message = "创建时间不能填") @JsonFormat(pattern = "yyyy-MM-dd", locale = "zh", timezone = "GMT+8") private Date createTime;

@URL(message = "url填写错误") private String url; } </code></pre> <h4>3.2 Web层数据接收</h4> <p>只需要加上@Valid注解即可,然后通过BindingResult来接收校验错误。</p> <pre><code class="java"> @RequestMapping(value = "/test") public List<String> set(@Valid @RequestBody UserInfo userInfo, BindingResult bindingResult) { if (bindingResult.hasErrors()) { List<String> errorMsg = bindingResult.getAllErrors().stream().map(s -> s.getDefaultMessage()) .collect(Collectors.toList()); return errorMsg; } return Collections.singletonList("0000"); } </code></pre> <p>这里,是打印了所有错误结果,如果只校验是否错误,抛出第一个错误,这样写即可:</p> <pre><code class="java">@RequestMapping(value = "/test") public List<String> set(@Valid @RequestBody UserInfo userInfo, BindingResult bindingResult) { if (bindingResult.hasErrors()) { String errorMsg = bindingResult.getAllErrors().get(0).getDefaultMessage(); return Collections.singletonList(errorMsg); } return Collections.singletonList("0000"); } </code></pre> <h4>3.3 校验不通过测试</h4> <pre><code>请求参数: { "createTime":"2018-08-09", "userName": "", "name": " ", "age": 9, "mobile": "123123123", "girlFrinds": ["1号","2号","3号"], "money": 101, "temperatureWinter": 0, "temperatureSummer": -1, "address": "12", "people": false, "delete": true, "password": "123", "email": "11@", "expireTime":"2019-11-11", "birthDate":"2020-11-11", "url":"qwe" } 返回结果: [ "你女朋友个数在0-2之间", "地址在4-64之间", "密码格式错误", "email格式错误", "创建时间不能填", "你钱包里的钱在0-2之间", "对象必须是人", "出生日期比当前时间早", "冬天温度在0°以下", "年龄太小了", "失效时间比当前时间晚", "url填写错误", "夏天温度在0°以上", "不能上来就删除", "姓名不能为空或空字符串", "用户名不能为空" ] </code></pre> <h4>3.4 校验通过测试</h4> <pre><code>请求参数: { "createTime":"", "userName": " ", "name": "cff", "age": 11, "mobile": "13333333333", "girlFrinds": ["1号","2号"], "money": 100, "temperatureWinter": -1, "temperatureSummer": 12, "address": "12345", "people": true, "delete": false, "password": "123456", "email": "11@qq.com", "expireTime":"2020-11-11", "birthDate":"2019-11-11", "url":" http://www. pomit.cn " } 返回结果: [ "0000" ] </code></pre> <h3>四、级联校验</h3> <p>如果一个对象持有另一个对象的引用,可以使用@Valid注解进行级联校验。 如下所示:</p> <h4>4.1 实体</h4> <pre><code class="java">package com.cff.springbootwork.validator.vo; import javax.validation.Valid; import javax.validation.constraints.NotEmpty; import javax.validation.constraints.NotNull; import lombok.AllArgsConstructor; import lombok.Builder; import lombok.Data; import lombok.NoArgsConstructor; @Data @NoArgsConstructor @AllArgsConstructor @Builder public class UserRole { @NotEmpty(message = "用户名不能为空") private String userName; @NotNull(message = "roleId不能为空") private Integer roleId; @Valid private UserInfo userInfo; } </code></pre> <h4>4.2 测试Web</h4> <pre><code class="java">@RequestMapping(value = "/test1") public List<String> test1(@Valid @RequestBody UserRole userRole, BindingResult bindingResult) { if (bindingResult.hasErrors()) { List<String> errorMsg = bindingResult.getAllErrors().stream().map(s -> s.getDefaultMessage()) .collect(Collectors.toList()); return errorMsg; } return Collections.singletonList("0000"); } </code></pre> <h4>4.3 测试结果</h4> <pre><code>请求数据: { "userName": "", "roleId": 1, "userInfo":{ "createTime":"2018-08-09", "userName": "", "name": " ", "age": 9, "mobile": "123123123", "girlFrinds": ["1号","2号","3号"], "money": 101, "temperatureWinter": 0, "temperatureSummer": -1, "address": "12", "people": false, "delete": true, "password": "123", "email": "11@", "expireTime":"2019-11-11", "birthDate":"2020-11-11", "url":"qwe" } } 返回结果: [ "失效时间比当前时间晚", "用户名不能为空", "用户名不能为空", "你女朋友个数在0-2之间", "密码格式错误", "你钱包里的钱在0-2之间", "姓名不能为空或空字符串", "url填写错误", "冬天温度在0°以下", "对象必须是人", "email格式错误", "不能上来就删除", "年龄太小了", "夏天温度在0°以上", "地址在4-64之间", "创建时间不能填", "出生日期比当前时间早" ] </code></pre> <h3>五、手动校验</h3> <p>有时候,不用使用@Valid 自动校验,需要手动调起validator进行校验,可以使用<code>validator.validate(roleInfo);</code>进行校验:</p> <h4>5.1 实体</h4> <pre><code class="java">package com.cff.springbootwork.validator.vo; import javax.validation.constraints.NotEmpty; import javax.validation.constraints.NotNull; import lombok.AllArgsConstructor; import lombok.Builder; import lombok.Data; import lombok.NoArgsConstructor; @Data @NoArgsConstructor @AllArgsConstructor @Builder public class RoleInfo { @NotNull(message = "roleId不能为空") private Integer roleId; @NotEmpty(message = "roleName不能为空") private String roleName; } </code></pre> <h4>5.2 测试</h4> <p>Validator(import javax.validation.Validator;) 在SpringBoot中,可以作为bean之间被注入。</p> <pre><code class="java">@Autowired Validator validator; @RequestMapping(value = "/test2") public List<String> test2(@RequestParam("roleId") Integer roleId, @RequestParam("roleName") String roleName) { RoleInfo roleInfo = new RoleInfo(roleId, roleName); Set<ConstraintViolation<RoleInfo>> sets = validator.validate(roleInfo); if(sets.isEmpty())return Collections.singletonList("0000"); List<String> errorMsg = sets.stream().map(s -> s.getMessage()).collect(Collectors.toList()); return errorMsg; } </code></pre> <h3>六、分组校验</h3> <p>分组校验就是处理特殊情况下的校验,使不同的调用走不同的校验组。</p> <p>如,一个对象A持有另一个对象B的引用,对象B中某些字段不想在对象A校验的时候被校验到,可以使用分组校验。</p> <h4>6.1 实体</h4> <p>假设有两个实体:</p> <pre><code class="java">import javax.validation.Valid; import javax.validation.constraints.NotEmpty; import javax.validation.constraints.NotNull; import lombok.AllArgsConstructor; import lombok.Builder; import lombok.Data; import lombok.NoArgsConstructor; @Data @NoArgsConstructor @AllArgsConstructor @Builder public class UserRoleInfo { @NotEmpty(message = "用户名不能为空") private String userName; @NotNull(message = "roleId不能为空") private Integer roleId; @Valid private RoleInfo roleInfo; } </code></pre> <pre><code class="java">import javax.validation.constraints.NotEmpty; import javax.validation.constraints.NotNull; import lombok.AllArgsConstructor; import lombok.Builder; import lombok.Data; import lombok.NoArgsConstructor; @Data @NoArgsConstructor @AllArgsConstructor @Builder public class RoleInfo { @NotNull(message = "roleId不能为空", groups=RoleGroup.class) private Integer roleId; @NotEmpty(message = "roleName不能为空", groups=RoleGroup.class) private String roleName; } </code></pre> <p>注意,这里的groups必须是接口。接口内容任意,只是个标识而已。</p> <pre><code class="java">public interface RoleGroup { } </code></pre> <p><strong><code>Default.class(javax.validation.groups.Default)</code>是默认分组,不需要自己建立.</strong></p> <h4>6.2 测试不带分组</h4> <pre><code class="java">import java.util.Collections; import java.util.List; import java.util.Set; import java.util.stream.Collectors; import javax.validation.ConstraintViolation; import javax.validation.Validator; import javax.validation.groups.Default; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; import com.cff.springbootwork.validator.vo.RoleGroup; import com.cff.springbootwork.validator.vo.RoleInfo; import com.cff.springbootwork.validator.vo.UserRoleInfo; @RestController @RequestMapping("/valid") public class ValidatorRest { @Autowired Validator validator; @RequestMapping(value = "/test3") public List<String> test3(@RequestParam("roleId") Integer roleId, @RequestParam("userName") String userName, @RequestParam("roleName") String roleName) { UserRoleInfo userRoleInfo = new UserRoleInfo(); userRoleInfo.setRoleId(roleId); userRoleInfo.setUserName(userName); RoleInfo roleInfo = new RoleInfo(roleId, roleName); userRoleInfo.setRoleInfo(roleInfo); Set<ConstraintViolation<UserRoleInfo>> sets = validator.validate(userRoleInfo); if (sets.isEmpty()) return Collections.singletonList("0000"); List<String> errorMsg = sets.stream().map(s -> s.getMessage()).collect(Collectors.toList()); return errorMsg; } } </code></pre> <p>结果:</p> <pre><code>请求参数: roleId:1 userName: roleName: 返回结果: [ "用户名不能为空" ] </code></pre> <h4>6.2 测试带分组</h4> <p>注意,<code>Default.class</code>是默认分组。</p> <pre><code class="java">import java.util.Collections; import java.util.List; import java.util.Set; import java.util.stream.Collectors; import javax.validation.ConstraintViolation; import javax.validation.Validator; import javax.validation.groups.Default;

userRoleInfo.setRoleId(roleId); userRoleInfo.setUserName(userName); RoleInfo roleInfo = new RoleInfo(roleId, roleName); userRoleInfo.setRoleInfo(roleInfo); Set<ConstraintViolation<UserRoleInfo>> sets = validator.validate(userRoleInfo, RoleGroup.class, Default.class); if (sets.isEmpty()) return Collections.singletonList("0000"); List<String> errorMsg = sets.stream().map(s -> s.getMessage()).collect(Collectors.toList()); return errorMsg; } } </code></pre> <p>结果:</p> <pre><code>请求参数: roleId:1 userName: roleName: 返回结果: [ "roleName不能为空", "用户名不能为空" ] </code></pre> <h3>七、自定义注解校验</h3> <p>有时候,我们仍需要自定义校验注解,如,我这里定义一个只校验0或1数据的验证器。</p> <h4>7.1 自定义注解</h4> <pre><code class="java">package com.cff.springbootwork.validator.custom; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; import javax.validation.Constraint; import javax.validation.Payload; /** * 自定义类校验注解 * 作用于类,用以校验0/1类型数据 * @author cff * */ @Target(value = {ElementType.FIELD}) @Retention(RetentionPolicy.RUNTIME) @Constraint(validatedBy=TypeZeroOneValidator.class) public @interface ZeroOne { String message() default "参数有误"; Class<?>[] groups() default {}; Class<? extends Payload>[] payload() default {}; } </code></pre> <h4>7.2 自定义Validator</h4> <pre><code class="java">package com.cff.springbootwork.validator.custom; import javax.validation.ConstraintValidator; import javax.validation.ConstraintValidatorContext; public class TypeZeroOneValidator implements ConstraintValidator<ZeroOne, Object> { @Override public void initialize(ZeroOne constraintAnnotation) { } @Override public boolean isValid(Object obj, ConstraintValidatorContext context) { if (obj == null) return true; int curNum = 0; if (obj instanceof String) { String s = (String) obj; curNum = Integer.parseInt(s); } else if (obj instanceof Boolean) { boolean b = ((Boolean) obj).booleanValue(); if (b) { curNum = 1; } } else if (obj instanceof Long) { curNum = ((Long) obj).intValue(); } else { curNum = ((Integer) obj).intValue(); } if (curNum == 0 || curNum == 1) return true; return false; } } </code></pre> <h4>7.3 测试实体</h4> <pre><code class="java">package com.cff.springbootwork.validator.vo;
