spring boot: java.lang.AbstractMethodError: org.apache.bval.jsr303.ApacheValidatorFactory.close()V

今天在用spring boot啟動服務時發生了如下的異常：

[main][ERROR] (SpringApplication.java:771) Application startup failed java.lang.AbstractMethodError: org.apache.bval.jsr303.ApacheValidatorFactory.close()V at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.springframework.util.ReflectionUtils.invokeMethod(ReflectionUtils.java:216) at org.springframework.util.ReflectionUtils.invokeMethod(ReflectionUtils.java:201) at org.springframework.validation.beanvalidation.LocalValidatorFactoryBean.close(LocalValidatorFactoryBean.java:428) at org.springframework.validation.beanvalidation.LocalValidatorFactoryBean.destroy(LocalValidatorFactoryBean.java:434) at org.springframework.boot.context.properties.ConfigurationPropertiesBindingPostProcessor.freeLocalValidator(ConfigurationPropertiesBindingPostProcessor.java:233) at org.springframework.boot.context.properties.ConfigurationPropertiesBindingPostProcessor.onApplicationEvent(ConfigurationPropertiesBindingPostProcessor.java:220) at org.springframework.boot.context.properties.ConfigurationPropertiesBindingPostProcessor.onApplicationEvent(ConfigurationPropertiesBindingPostProcessor.java:77) at org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener(SimpleApplicationEventMulticaster.java:172) at org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener(SimpleApplicationEventMulticaster.java:165) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:139) at org.springframework.context.support.AbstractApplicationContext.publishEvent(AbstractApplicationContext.java:393) at org.springframework.context.support.AbstractApplicationContext.publishEvent(AbstractApplicationContext.java:347) at org.springframework.context.support.AbstractApplicationContext.finishRefresh(AbstractApplicationContext.java:883) at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.finishRefresh(EmbeddedWebApplicationContext.java:144) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:546) at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.refresh(EmbeddedWebApplicationContext.java:122) at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:693) at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:360) at org.springframework.boot.SpringApplication.run(SpringApplication.java:303) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1118) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1107) …

上面的異常直接原因就是 org.apache.bval.jsr303.ApacheValidatorFactory(org.apache.bval:bval-jsr303:0.5)沒有close方法. 進一步究期原因是 ApacheValidatorFactory 所實現的介面ValidatorFactory的早期版本是沒有close方法的，而spring 4用的 org.hibernate:hibernate-validator:5.3.6.Final用到的ValidatorFactory版本更高,定義了cloase方法 更進一步，在項目啟動時陰錯陽差的SPI載入ValidatorFactory實例時先找到了ApacheValidatorFactory，而非spring4需要的HibernateValidatorFactory，所以就報錯了。 解決的辦法么，也很直接：把org.apache.bval:bval-jsr303排除掉

總結： spring4.0 之後不在支援 jsr303,所以如果項目中有混入jsr303就要將之排除掉，類似如下修改pom.xml，

		<dependency>  			<groupId>${project.groupId}</groupId>  			<artifactId>faceapi-thriftservice</artifactId>  			<version>${faceapi.version}</version>  			<!-- spring4.0 之後不再支援 jsr303，如果不排除會導致 AbstractMethodError 異常 -->  			<exclusions>  				<exclusion>  					<groupId>org.apache.bval</groupId>  					<artifactId>bval-jsr303</artifactId>  				</exclusion>  			</exclusions>  		</dependency>
