pure-validation可配置、无侵入、易拓展、热加载、轻量级动态参数验证框架
pure-validation一款可配置、无侵入、易拓展、热加载、轻量级的动态参数验证框架，可替代hibernate-validation，代码总数不足1000行，简单易学，也可以自行拓展实现更多验证器validator，有需要star一下。
github： https://github.com/purestackorg/pure-validation
默认包含多个通用验证实现
<?xml version="1.0" encoding="UTF-8"?>
<validators>
<validator name="required" class="com.purestack.common.validation.validators.RequiredValidator"/>
<validator name="pattern" class="com.purestack.common.validation.validators.PatternValidator"/>
<validator name="size" class="com.purestack.common.validation.validators.SizeValidator"/>
<validator name="min" class="com.purestack.common.validation.validators.MinValidator"/>
<validator name="max" class="com.purestack.common.validation.validators.MaxValidator"/>
<validator name="equals" class="com.purestack.common.validation.validators.EqualsValidator"/>
<validator name="timestampMax" class="com.purestack.common.validation.validators.TimestampMaxValidator"/>
<validator name="timestampMin" class="com.purestack.common.validation.validators.TimestampMinValidator"/>
<validator name="decimalMax" class="com.purestack.common.validation.validators.DecimalMaxValidator"/>
<validator name="decimalMin" class="com.purestack.common.validation.validators.DecimalMinValidator"/>
<validator name="spring" useSpring="true" class="com.purestack.common.validation.validators.SpringValidator"/>
</validators>
- 定义全局规则配置，引入各个实体验证规则
<?xml version="1.0" encoding="UTF-8"?>
<validation>
<!-- include 标签导入其他配置 -->
<include file="validation/user.rule.xml"/>
<include file="validation/article.rule.xml"/>
</validation>
- 定义user和article实体验证规则
user.rule.xml规则
<?xml version="1.0" encoding="UTF-8"?>
<validation>
<!-- 验证组ID，全局唯一 -->
<group name="user.rule">
<!-- 验证字段 -->
<field name="email">
<rule name="required" message="邮件必须填写"/>
<rule name="size" message="邮件长度应该3-100之间">
<param name="min" value="3"/>
<param name="max" value="100"/>
</rule>
<rule name="pattern" message="邮件格式不正确">
<param name="regex" value="^[A-Za-z]+[\.\-_A-Za-z0-9]*@[A-Za-z0-9]+[\.\-_A-Za-z0-9]*$"/>
</rule>
</field>
<field name="password">
<rule name="required" message="密码必须填写" />
<rule name="min" message="密码至少8个字符">
<param name="value" value="9" />
</rule>
<rule name="max" message="密码最多20个字符">
<param name="value" value="20" />
</rule>
<rule name="equals" message="两次密码输入不正确">
<param name="target" value="passwordOne" />
</rule>
</field>
<field name="starttime">
<rule name="timestampMax" message="开始时间不能大于结束时间">
<param name="target" value="endtime" />
</rule>
</field>
<field name="endtime">
<rule name="timestampMin" message="结束时间不能小于开始时间">
<param name="target" value="starttime" />
</rule>
</field>
<field name="age">
<rule name="decimalMin" message="年龄要大于30岁">
<param name="value" value="30" />
</rule>
<rule name="decimalMax" message="年龄要小于或等于50岁">
<param name="inclusive" value="true" />
<param name="value" value="50" />
</rule>
</field>
<field name="address">
<rule name="required" message="地址必须填写" />
</field>
<field name="postcode">
<rule name="equals" message="邮编必须为440000">
<param name="value" value="440000" />
</rule>
</field>
<field name="stars">
<rule name="decimalMin" message="星星数量要大于5">
<param name="value" value="5" />
</rule>
</field>
</group>
</validation>
article.rule.xml规则
```xml
<?xml version="1.0" encoding="UTF-8"?>
<validation>
<!-- 验证组ID，全局唯一 -->
<group name="article.rule">
<!-- 验证字段 -->
<field name="text">
<!-- 规则列表 -->
<rule name="required" message="内容必須填寫" />
<rule name="between" message="长度应该100-10000之间">
<param name="min" value="100" />
<param name="max" value="10000" />
</rule>
</field>
</group>
</validation>
- 定义测试实体类
import java.sql.Timestamp;
/**
* 用户对象
*
*/
public class User {
// 用户名
private String username;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
// 密码
private String password;
// 确认密码
private String passwordOne;
// 邮箱
private String email;
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getPostcode() {
return postcode;
}
public void setPostcode(String postcode) {
this.postcode = postcode;
}
public Double getStars() {
return stars;
}
public void setStars(Double stars) {
this.stars = stars;
}
private String address;
private String postcode;
private Double stars;
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
private Integer age;
private Timestamp starttime;
private Timestamp endtime;
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getPasswordOne() {
return passwordOne;
}
public void setPasswordOne(String passwordOne) {
this.passwordOne = passwordOne;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Timestamp getStarttime() {
return starttime;
}
public void setStarttime(Timestamp starttime) {
this.starttime = starttime;
}
public Timestamp getEndtime() {
return endtime;
}
public void setEndtime(Timestamp endtime) {
this.endtime = endtime;
}
}
- 定义单元测试方法，查看效果
import com.purestack.common.validation.BasicValidateService;
import com.purestack.common.validation.IValidateService;
import com.purestack.common.validation.ValidationResult;
import com.purestack.common.validation.config.BasicValidateConfig;
import com.purestack.common.validation.config.IValidateConfig;
import org.junit.jupiter.api.Test;
import java.sql.Timestamp;
import java.util.Calendar;
import org.apache.log4j.Logger;
public class ValidationTest {
private static Logger logger = Logger.getLogger(ValidationTest.class);
@Test
public void testValid() {
// 验证器配置，系统默认配置
String validatorsXML = "validation/validators.xml";
// 规则配置
String rulesXML = "validation/rules.xml";
/**
* 实例化配置对象
*/
IValidateConfig config =new BasicValidateConfig(validatorsXML, rulesXML);
/**
* 实例化验证服务层
*/
IValidateService validateService = new BasicValidateService(config);
// 实例化用户
User user = createUser();
/**
* 执行验证
*/
ValidationResult result = validateService.validate(user, "user.rule");
// 输出结果
if(result.isValid()) {
logger.info("验证成功.");
} else {
logger.info("验证失败，结果如下");
logger.info(result.getErrors());
}
}
public User createUser(){
User user = new User();
user.setEmail("test#purestack.cc");
user.setPassword("123");
user.setPasswordOne("abc");
user.setAge(70);
user.setPostcode("4422222");
Calendar date = Calendar.getInstance();
user.setStarttime(new Timestamp(date.getTimeInMillis()));
user.setEndtime(new Timestamp(date.getTimeInMillis()-1000));
return user;
}
}
简单的4个步骤即可完成动态配置验证规则，简单方便，你值得拥有！
