建网站做cpa,wordpress 投票插件,昆明建设工程质量备案在哪个网站,展示型网站建设日常开发过程中#xff0c;总会遇到各种小问题#xff0c;特此记录下各种解决。 1. eclipse中部署项目到tomcat#xff0c;启动tomcat时报错#xff1a; Resource is out of sync with the file system: ................ 太长只截取前一段#xff0c;解决办法#xff…日常开发过程中总会遇到各种小问题特此记录下各种解决。 1. eclipse中部署项目到tomcat启动tomcat时报错 Resource is out of sync with the file system: ................ 太长只截取前一段解决办法需要手动刷新一下资源管理器eclipse中工程目录右键refresh。 2.maven项目打包的时候mybatis的*mapper.xml都没得打包解决方法pom.xml中build节点中加入 resourcesresourcedirectorysrc/main/java/directoryincludesinclude**/*.xml/include/includesfilteringfalse/filtering/resource/resources 3.mybatis的数据库连接配置信息写在properties配置文件中然后做spring做单元测试的时候总是报出 Could not load driverClass ${jdbc.driverClass} 错误的原因很明显相关的连接参数信息并没有正确的去读取properties配置文件中的相关信息本地项目使用的mybaits版本号3.1.1。网上查找解决办法是由于 bean classorg.mybatis.spring.mapper.MapperScannerConfigurerproperty namebasePackage valuecom.reserve.core.dao /property namesqlSessionFactory refsqlSessionFactory/property
/bean 中的sqlSessionFactory注入问题改用sqlSessionFactoryBeanName注入就没有问题(不要使用sqlSessionFactory属性注入使用 sqlSessionFactoryBeanName注入)因为这时不会立即初始化sqlSessionFactory,传入的只是名字非bean 所以不会引发提前初始化问题。 property namesqlSessionFactoryBeanName valuesqlSessionFactory/property 4.获取泛型T.class。最近最项目中用到泛型设计但是要获取T.class方法如下 public abstract class DataSyncProServiceT extends Data implements DataSyncService{private ClassT entityClass;//获取泛型T的T.classpublic DataSyncProService(){Type genType getClass().getGenericSuperclass();Type[] params ((ParameterizedType) genType).getActualTypeArguments(); entityClass (Class) params[0]; }....
} 截取部分代码子类的构造函数会调用父类的构造函数所以当子类实例化的时候父类的entityClass 已经得到了T.class。 本地代码其中一个子类定义 public class MerinfoImpl extends DataSyncProServiceMerInfo 另外照搬一段资料虽然现在还不是很懂 这是泛型擦拭法使得Generic无法获取自己的Generic Type类型。实际上BadClassString()实例化以后Class里面就不包括T的信息了对于Class而言T已经被擦拭为Object而真正的T参数被转到使用T的方法或者变量声明或者其它使用T的地方里面如果没有那就没有存根所以无法反射到T的具体类别也就无法得到T.class。而getGenericSuperclass()是Generic继承的特例对于这种情况子类会保存父类的Generic参数类型返回一个ParameterizedType这时可以获取到父类的T.class了这也正是子类确定应该继承什么T的方法 5.jquery修改css中带有!important的样式属性 html : select classselect1 idjq-sql-content/select
外部样式为 .select1{color: #e3e3e3!important;}
如果直接使用$(#jq-sql-content).css(color,black)或者$(#jq-sql-content).css(color,black!important),都是无效的
正确用法$(#jq-sql-content).css(cssText,colorblack!important),多个属性的话$(#jq-sql-content).css(cssText,colorblack!important;属性名:值!important;) 6、linux安装activemq 安装完毕之后启动时候报错如下 2018-06-05 11:26:06,750 | WARN | Exception thrown from LifecycleProcessor on context close | org.apache.activemq.xbean.XBeanBrokerFactory$1 | main
