开始Hibernate 3.5 - ant任务的问题

Ste*_*all 5 java ant hibernate slf4j

我正在努力完成"Beginning Hibernate 3.5",我遇到了一个初步障碍.

当我运行时ant exportDDL,我收到以下错误:

exportDDL:
   [htools] Executing Hibernate Tool with a Hibernate Annotation/EJB3 Configuration
   [htools] 1. task: hbm2ddl (Generates database schema)
   [htools] SLF4J: The requested version 1.6 by your slf4j binding is not compatible with [1.5.5, 1.5.6, 1.5.7, 1.5.8]
   [htools] SLF4J: See http://www.slf4j.org/codes.html#version_mismatch for further details.

使用以下ant任务:

<target name="exportDDL" depends="compile">
    <mkdir dir="${sql}"/>
    <htools destdir="${sql}">
        <classpath refid="classpath.tools"/>
        <annotationconfiguration
                configurationfile="${src}/hibernate.cfg.xml"/>
        <hbm2ddl drop="true" outputfilename="sample.sql"/>
    </htools>
</target>
<target name="compile">
    <javac srcdir="${src}" destdir="${bin}" classpathref="classpath.base"/>
</target>

这里发生了什么?ant compile工作正常,但exportDDL任务没有.sl4j jar在classpath上,我下载了slf4j-simple-1.6.1.jar.思考?

这里解决了你想要的

混合混合不同版本的slf4j工件可能会导致问题.例如,如果你正在使用SLF4J的API-1.6.1.jar,那么你应该也使用SLF4J-简单1.6.1.jar,用SLF4J-简单1.5.5.jar将无法正常工作.

通常,您应该确保slf4j-api版本与slf4j绑定的版本匹配.

在初始化时,如果SLF4J怀疑可能存在版本不匹配问题,它将发出有关可疑不匹配的警告.有关版本不匹配检测机制的确切详细信息,请参阅常见问题解答中的相关条目.
