Spring Boot开启参数校验，整合`hibernate-validator`；

Running with Spring Boot v2.1.15.RELEASE, Spring v5.1.16.RELEASE

# 配置 #

import org.hibernate.validator.HibernateValidator;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.validation.beanvalidation.MethodValidationPostProcessor;
    
    import javax.validation.Validation;
    import javax.validation.Validator;
    
    @Configuration
    public class ValidatorConfig { 
    
        @Bean
        public static Validator validator() { 
            return Validation
                    .byProvider(HibernateValidator.class)
                    .configure()
                    .failFast(true)
                    .buildValidatorFactory()
                    .getValidator();
        }
    
        @Bean
        public MethodValidationPostProcessor methodValidationPostProcessor() { 
            MethodValidationPostProcessor processor = new MethodValidationPostProcessor();
            processor.setValidator(validator());
            return processor;
        }
    }

# 引入依赖 #

<hibernate-validator.version>6.0.20.Final</hibernate-validator.version>

<dependency>
        <groupId>org.hibernate.validator</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>${hibernate-validator.version}</version>
    </dependency>

# 使用方式 #

public void login(@Valid UserLoginVo vo) { 
    
        // TODO:
    }

# 其他 #

如果报错：提示找不到`javax/el/ELManager`，引入下面的包；因为有些项目是以`provided`形式引入的。

<dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-el</artifactId>
        <version>9.0.36</version>
    </dependency>
