今天在用spring boot啓動服務時發生瞭如下的異常：
[main][ERROR] (SpringApplication.java:771) Application startup failed

…
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 所實現的接口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，在項目啓動時陰錯陽差的SPI加載ValidatorFactory實例時先找到了ApacheValidatorFactory，而非spring4需要的HibernateValidatorFactory，所以就報錯了。
解決的辦法麼，也很直接：把org.apache.bval:bval-jsr303排除掉
總結：
spring4.0 之後不在支持 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 之後不再支持 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>
