我刚刚在带有Spring Initializr的IntelliJ IDEA 2016.3.4上使用Spring Boot(1.5.2.BUILD- SNAPSHOT)创建了一个项目。
当我尝试运行项目时,由于ApplicationEventMulticaster和methodValidationPostProcessor而导致异常。

根据对这个问题的建议,我试图在我的POM上添加另一个版本的hibernate-validator,但错误仍然存在。
解决
由于某种原因,artefact spring-boot-starter-web向hibernate- validator添加了一个依赖项,因此spring希望我配置一个校验器依赖项。
我已删除该依赖项,在我的pom.xml中添加了排除项。
<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>
我添加了更多的依赖项,包括JPA,并且仍然可以正常工作。
