Spring MVC上下文扫描，带有多个调度程序servlet和maven叠加层

标签： spring maven spring-mvc servlets

我正在构建一个带有弹簧的模块化Web应用程序，使用maven覆盖来组合主Web应用程序上的不同模块。这两个应用程序都是标准的maven-archetype-webapp结构。为了进行测试，我创建了一个名为“portal”的项目，它将成为主要的战争，以及一个“hello”项目，它将被重叠到主战争上。主要文件是：

门户网站（主要）应用 web.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"

应用上下文

        class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
        <property name="order" value="1" />
    </bean>
</beans>

主要-servlet.xml中 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

                    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
                    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd">
    <mvc:annotation-driven />
    <context:component-scan base-package="pt.fhc.fmc.web" />
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

你好-servlet.xml中 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
                    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd     
                    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
                    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd">

    <mvc:annotation-driven />
    <context:component-scan base-package="pt.fhc.fmc.modules.hello" ></context:component-scan>

    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

另外，我有两个测试控制器。一个在模块上：

package pt.fhc.fmc.modules.hello;
// Standard spring imports.

@Controller
public class HelloController {

    @Autowired
    TestService testService;

    @RequestMapping(value = "/hello", method = RequestMethod.GET)
    public ModelAndView home(Locale locale) {

        ModelAndView model = new ModelAndView("helloview");
        return model;
    }
}

另一个在主项目（门户网站）上：

package pt.fhc.fmc.web.controllers;

@Controller
public class HomeController {
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public ModelAndView  home(Locale locale) {

        ModelAndView model = new ModelAndView("home");
        return model;
    }
}

主要的pom.xml（在门户网站上）

                    </overlays>
                </configuration>

            </plugin>

            <plugin>

                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

问题是，在上下文扫描期间找不到控制器。可能缺少什么？

我正在使用Widfly 9.0.2和Spring 4.2

1 个答案:

答案 0 :(得分：0)

最终通过重新安装WildFly解决了这个问题。上面的配置适用于多个调度程序servlet，maven将多个Web项目组合成一个可部署的战争。
