使用AppFuse1.8.2遇到的问题
内容提要
这个部分将说明使用AppFuse1.8.2遇到的问题以及如何解决这些问题。
- 我会用这种格式说明我在 实际过程 中的操作。
目录
- 导入Eclipse以后无法编译
- 运行ant setup-db无法正确创建数据库
- 使用ant deploy无法发布应用
- 中文乱码问题
- 我实际使用的是webwork+spring+ hibernate遇到的，可能有些地方与默认的struts+spring+hibernate不一样，有些问题是使用了webwork引出的。使用本文提供的例子需要在创建自己的应用后运行ant install-webwork。
导入Eclipse以后有无法编译
在Eclipse中将新创建的Myapp工程导入（import）后，Eclipse提示struts.jar和struts-el.jar两个包找不到。需要手工在Eclipse中把工程对这两个包的引用移除掉。
另外webwork相关的包引用没有添加到工程中，需要手工加入。至此Eclipse可以正常编译整个工程。
如果想彻底解决这个问题，应该考虑修改install-webwork任务。这个问题对使用影响不大，所以我就没有研究了。:-)
运行ant setup-db无法正确创建数据库
会出现app_user表无法创建的错误：
[schemaexport] (hbm2ddl.SchemaExport 167 ) Unsuccessful: create table app_user (username varchar(20) not null, version integer not null, password varchar(255) not null, first_name varchar(50) not null, last_name varchar(50) not null, address varchar(150), city varchar(50) not null, province varchar(100), country varchar(100), postal_code varchar(15) not null, email varchar(255) notnull unique, phone_number varchar(255), website varchar(255), password_hint varchar(255), enabled bit, primary key (username))[schemaexport] (hbm2ddl.SchemaExport 168 ) Specified key was too long. Max key length is 500
具体错误和解决办法可以参考AppFuse实践一——配置安装 
。
- AppFuse 1.8.1因为DBUnit的关系也会出现无法创建表的问题，这个问题在1.8.2已经改过来了。
使用ant deploy无法发布应用
运行ant setup-db创建数据库，运行ant setup-tomcat正确配置Tomcat以后，运行ant deploy发布应用会碰到下面的问题：
BUILD FAILEDC:\Myapp\build.xml:285: xdoclet.XDocletException: Couldn't find template: C:\Myapp\metadata\templates\struts_form.xdt
检查build.xml 285行，发现下面的的关于gen-forms的ant任务定义
<!-- Generate ActionForms from POJOs --> <target name="gen-forms" depends="prepare" unless="webdoclet.uptodate" description="Generates ActionForms from POJOs"> <taskdef name="xdoclet" classname="xdoclet.DocletTask" classpathref="xdoclet.classpath"/> <!-- generate struts forms --> <xdoclet destdir="${build.dir}/web/gen" excludedtags="@version,@author" addedtags="@xdoclet-generated at ${TODAY}" force="${xdoclet.force}" mergedir="metadata/web"> <fileset dir="src/dao"/> <!-- generate struts forms --> <actionform templateFile="metadata/templates/struts_form.xdt"> <packageSubstitution packages="model" substituteWith="webapp.form"/> </actionform> </xdoclet> </target>这个任务是使用struts用到的，使用webwork不需要用，去掉compile-web任务对gen-forms的引用，把build.xml文件中的的296行
<target name="compile-web" depends="package-service,stage-web,gen-forms" description="Compile web module">
修改成
<target name="compile-web" depends="package-service,stage-web" description="Compile web module">
然后再运行ant deploy，出现好多错

[javac] Consult the following stack trace for details. [javac] java.lang.OutOfMemoryErrorBUILD FAILED肯定是编译路径中没有加入webwork相关包的引用！手工修改Myapp目录下面properties.xml文件，加入webwork相关包的引用，在properties.xml文件第146行后面加上新的一行
<fileset dir="${webwork.dir}" includes="*.jar"/>然后运行ant deploy 还是出错
BUILD FAILEDC:\myfile\Myapp\build.xml:54: C:\myfile\Myapp\build\web\gen not found.
去掉build.xml第54行
<srcfiles dir="${build.dir}/web/gen" includes="**/*.java"/>还有第320行
<fileset dir="${build.dir}/web/gen"/>- 实际上把这两句注释掉就可以了，这个是前面那个gen-forms任务用到的输出目录。
运行ant deloy，启动tomcat，可以正常工作了!
中文乱码问题
界面上可以看到中文字符无法正常显示，有很多“?”。
怀疑是ApplicationResources_zh_CN.properties文件有问题，用eclipse打开编辑（在web\WEB-INF\classes目录下），果然看到是乱码。把早期版本的文件内容copy过来覆盖重新发布，一切正常了!
