【日常错误】Could not initialize class org.hibernate.validator.internal.engine.ConfigurationImpl

最近在用spring-boot编写一个Lucene项目，中间用到了redis，引用了spring-boot-starter-data-redis，在eclipse中用外部Tomcat启动项目一切正常，但是在运行Junit测试用例或使用spring-boot的application的main方法启动项目时，会报如下错误：

 2017-11-01 16:45:20.166  WARN 14252 --- [           main] o.s.w.c.s.GenericWebApplicationContext   : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'buildController': Unsatisfied dependency expressed through field 'redisTemplate'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'redisConfig': Unsatisfied dependency expressed through field 'redisConnectionFactory'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration$RedisConnectionConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.redis-org.springframework.boot.autoconfigure.data.redis.RedisProperties': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.validator.internal.engine.ConfigurationImpl

搜索堆栈中错误信息，很多博客都说是  hibernate-validator  版本冲突的问题：

于是尝试在pom文件中exclude排除spring-boot中自带的这个jar包：

在pom.xml代码里的配置变为如下：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.hibernate</groupId>
                    <artifactId>hibernate-validator</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

解决。
