我的APPFUSE开发问题记录

    1.怎样使每次测试时不删除数据库中表结构？
    解答：将pom.xml配置中的如下代码屏蔽掉。

<!--plugin>                                 <groupId>org.codehaus.mojo</groupId>                                 <artifactId>hibernate3-maven-plugin</artifactId>                                 <version>2.0-alpha-2</version>                                 <configuration>                                         <components>                                                 <component>                                                         <name>hbm2ddl</name>                                                         <implementation>                                                                 annotationconfiguration                                                         </implementation>                                                 </component>                                         </components>                                         <componentProperties>                                                 <drop>true</drop>                                                 <jdk5>true</jdk5>                                                 <propertyfile>                                                         target/classes/jdbc.properties                                                 </propertyfile>                                                 <skip>${maven.test.skip}</skip>                                         </componentProperties>                                 </configuration>                                 <executions>                                         <execution>                                                 <phase>process-test-resources</phase>                                                 <goals>                                                         <goal>hbm2ddl</goal>                                                 </goals>                                         </execution>                                 </executions>                                 <dependencies>                                         <dependency>                                                 <groupId>${jdbc.groupId}</groupId>                                                 <artifactId>${jdbc.artifactId}</artifactId>                                                 <version>${jdbc.version}</version>                                         </dependency>                                 </dependencies>                         </plugin-->

    2.怎样使用外部配置变量？
    解答：a。在pom.xml配置文件中加入占位符

<!-- FTP settings -->                     <ftp.url>135.224.82.4</ftp.url>                     <ftp.username>ls</ftp.username>                     <ftp.password>FdbEgT+7</ftp.password>                     <ftp.path>/data/jyf/0000/SRC/</ftp.path>           b。在resources目录下新建文本文件ftp.properties     ftp.url=${ftp.url}     ftp.username=${ftp.username}     ftp.password=${ftp.password}     ftp.path=${ftp.path}           c。在引用的applicationContext文件节点propertyConfigurer中添加<value>classpath:ftp.properties</value>           d。这时就可以直接使用占位符了     如：    <!--FTP Server-START-->             <bean id="myFTP" class="com.xjgzinfo.app.util.MyFTP"                     lazy-init="true" destroy-method="destroy">                     <property name="server" value="${ftp.url}" />                     <property name="user" value="${ftp.username}" />                     <property name="password" value="${ftp.password}" />                     <property name="path" value="${ftp.path}" />             </bean>             <!--FTP Server-END-->

    3.测试Dao时报如下错误该怎么解决？
    Unsatisfied dependency expressed through bean property 'interfaceDataDefineDao': Set this property value or disable dependency checking for this bean
    解答：解决方法1：测试初始化没有自动加载webapp/WEB-INF/applicationContext.xml文件，把该文件复制到target\classes\目录下即可。
          解决方法2：修改build path将src/main/webapp的out put folder修改成default output folder(实际是target/classes)，此方法实际是将webapp里的文件都复制到target/classes里，使得测试过程可以访问到applicationContext.xml文件。

    4.怎样解决测试报“Embedded error: java.sql.SQLException: ORA-01401: 插入的值对于列过大”错误？
    解答：检查hmb2ddl生成的数据表字段的实际类型及大小，再跟test/resources/samples-data.xml里对应的表的测试数据比较，检查是否跟实际数据库表中数据类型不匹配。有时appfuse自动产生的测试数据过大造成的，修改测试数据即可。
