java.lang.ClassNotFoundException：antlr.ANTLRException但我有项目的文件夹库中的antlr-2.7.6 [英] java.lang.ClassNotFoundException: antlr.ANTLRException but I have antlr-2.7.6 in folder lib of project

问题描述

 <？xml version =1.0encoding =UTF-8 ？> 
< classpath> 
< classpathentry kind =srcpath =src/> 
 ... 
 ... 
< classpathentry kind =libpath =lib / hibernate3.jar/> 
< classpathentry kind =libpath =lib / antlr-2.7.6.jar/> 
 ... 
< / classpath> 
  

添加了一些.jar。当我尝试这样做时：

 查询query2 = session.createQuery（sql2）; 
  

抛出异常问题名称：

java.lang.ClassNotFoundException：antlr.ANTLRException

任何想法？

预先致谢。

问候。

解决方案

这与Hibernate API有关。
如果我没有记错的话，Hibernate 3.0使用ANTLR（另一种语言识别工具）来处理HSQL查询。

您需要添加一个额外的jar（ANTLR-2.7.5H3.jar）到您的类路径。

或者你可以将下面的maven依赖关系添加到pom.xml中：

 <依赖性> 
< groupId> org.hibernate< / groupId> 
< artifactId> antlr< / artifactId> 
< version> 2.7.5H3< / version> 
< /依赖关系> 
  

I have this in .classpath:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
    ...
    ...
<classpathentry kind="lib" path="lib/hibernate3.jar"/>
<classpathentry kind="lib" path="lib/antlr-2.7.6.jar"/>
    ...
</classpath>

Some .jar added. When I try this:

Query query2 = session.createQuery(sql2);

throw exception in question name:

java.lang.ClassNotFoundException: antlr.ANTLRException

Any idea?

Thanks in advance.

Greetings.

解决方案

This is related to the Hibernate API. Hibernate 3.0 uses ANTLR (Another Tool for Language Recognition) for processing HSQL queries - if I remember correctly.
You need to add an additional jar (ANTLR-2.7.5H3.jar) to your classpath.

Or you can add the below maven dependency to the pom.xml

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>antlr</artifactId>
<version>2.7.5H3</version>
</dependency>
