Spring相关包引用 ![图片说明](https://img-ask.csdn.net/upload/201910/31/1572536093_691501.png) 本人在网上查询了很多方法,都说使用<mvc: resources .../>这个映射需要在其前面加上<mvc: annotation-driven />。但是我的项目里一开始配置springmvc的时候就已经有annotation-driven这个注解了,仍然无法访问静态资源。很是纳闷。然而使用<mvc: default-servlet-handler />这个注解就可以访问静态资源。再次发出问题,主要是想解决为什么annotation-driven这个注解不起作用,希望有过类似经验或者知道的朋友指导一下,甚是感激。小白,暂时没有币,还望不介意。

spring mvc 使用pom管理jar 包访问index.jsp 404 问题

在创建web project是选择了add maven surpport 项目结构:![图片说明](https://img-ask.csdn.net/upload/201612/30/1483066264_175003.png) web.xml文件: ``` <context-param> <param-name>contextConfigLocation</param-name> <!-- 应用上下文配置文件 --> <param-value>/WEB-INF/spring-servlet.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置spring核心servlet --> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--启动加载一次--> <load-on-startup>1</load-on-startup> </servlet> <!-- url-pattern配置为/,不带文件后缀,会造成其它静态文件(js,css等)不能访问。如配为*.do,则不影响静态文件的访问 --> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/view/</url-pattern> </servlet-mapping> ``` spring配置文件: ``` <!-- 启动注解驱动的Spring MVC功能,注册请求url和注解POJO类方法的映射--> <mvc:annotation-driven /> <!-- 启动包扫描功能,以便注册带有@Controller、@Service、@repository、@Component等注解的类成为spring的bean --> <context:component-scan base-package="com.sist.controller" > <context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/> </context:component-scan> <!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/view/" p:suffix=".jsp" /> <!-- 使用这种方式可以引用WEB-INF目录下的静态资源 --> <mvc:resources location="/WEB-INF/js/" mapping="/js/**" /> <mvc:annotation-driven > <!-- 消息转换器 spring需要3.1以上 --> <mvc:message-converters register-defaults="true"> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes" value="text/html;charset=UTF-8"/> </bean> </mvc:message-converters> </mvc:annotation-driven> <!-- 对静态资源文件的访问 不支持访问WEB-INF目录 --> <mvc:default-servlet-handler/> ``` 为什么会连index.jsp都访问不了啊?

Maven建立项目时的模块之间的依赖问题与单元测试的冲突

  问题是这样的:我用Maven建立的了个spring mvc 的demo.这个项目共有web,controller, service,dao,model,utils这几个module.然后,web依赖于controller,controller依赖于service,service依赖于dao,dao依赖于model,model依赖于utils,utils依赖于spring相关的jar.我把spring的配置文件放在了web下(因为是demo,所以只有一个文件,di使用的是注解),然后在web.xml中配置DispatcherServlet的时候加载spring的配置文件。   然后问题来了,因为这是个demo,我根本没想启动server,我只是想做些单元测试,但我发现按上面的方式建立项目,不启动server根本无法进入spring的环境。于是,我选择手动加载spring的context,我把手动加载context的代码放在了utils这个module中(其实这就是我加这个模块的目的).但是问题来了,因为spring配置文件在web中,所以我在utils 中“够不着”配置文件。我解决这个问题的方法是:让utils依赖于web,但后来发现这样就造成了依赖的循环。 好了,问题就是这样,我还试过一些其它的解决办法,但都遇到这样那样的问题,没有一种方法能令我满意。 所以我想问问大家,这个问题应该怎么解决,或者,你们平时是怎么建立项目的?

maven构建springmvc+ibatis,sqlmap文件不能访问试题Bean的问题

![图片说明](https://img-ask.csdn.net/upload/201508/26/1440578725_125804.png) 如图片所示,使用resources分结构之后就出现了这个问题,求各路大神指点~,一下是我得配置文件 web.xml ``` <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:*/**/applicationContext.xml, */**/applicationContext-*-bean.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:*/**/*-mvc.xml</param-value> </init-param> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </servlet> ``` spring文件 ``` <bean name="sqlDao" scope="prototype" class="com.icdc.sqldao.SqlDaoImpl" /> <bean name="loginService" scope="prototype" class="com.icdc.service.impl.LoginServiceImpl" /> ``` mvc文件 ``` <!-- 对包中的所有类进行扫描,以完成Bean创建和自动依赖注入的功能 需要更改 --> <context:component-scan base-package="com.icdc" > <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" /> </context:component-scan> <mvc:annotation-driven /> <!-- 启动Spring MVC的注解功能,完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> <!-- 防止jsp等静态资源被拦截 --> <mvc:default-servlet-handler /> ``` 我只是把主要的配置文件复制了出来,其他一切正常。如果将sqlmap的配置文件放在src/main/java路径下启动不报错,也可以正常访问数据库并查询出数据,放在src/main/resources下就报找不到这个bean的错误。

使用SSM框架配置式开发(不用注解),为何Service中无法注入Dao?
