org.apache.tomcat.util.bcel.classfile.ClassFormatException

解决方案

tomcat7 不能识别高版本 hibernate-core 中的JAVA语法，故降低版本号为 5.1.0.Final

javax.persistence.PersistenceException

解决方案

persistence.xml协议头版本更换为2.1匹配当前 org.hibernate:hibernate-core:5.1.0.Final

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
             xmlns="http://xmlns.jcp.org/xml/ns/persistence"

解决方案

引入依赖

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.el</artifactId>
    <version>3.0.1-b11</version>
</dependency>

javax.el相关异常

1. javax.validation.ValidationException Unable to load 'javax.el.ExpressionFactory'.

2. 信息: validateJarFile(/Users/tanpenggood/geek-training-camp/.extract/webapps/ROOT/WEB-INF/lib/javax.el-3.0.1-b11.jar) - jar not loaded. See Servlet Spec 2.on 9.7.2. Offending class: javax/el/Expression.class

3. have different Class objects for the type javax/el/ExpressionFactory used in the signature

解决方案

引入依赖，注意 scope 为 test。

即，仅在测试时需要，因为运行时tomcat内自带有相关依赖。

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.el</artifactId>
    <version>3.0.1-b11</version>
    <scope>test</scope>
</dependency>
