java - Hello World Spring MVC 与 Netbeans-6ren

java - Hello World Spring MVC 与 Netbeans

转载作者：行者123 更新时间：2023-11-30 03:34:46

我看到了所有与“spring mvc hello world”相关的问题，但在这种特殊情况下都无法帮助我(我正在使用注释方式)

我的结构很简单:

enter image description here

这些是我的配置文件:

web.xml

<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

<display-name>FirstSpringMVCProject</display-name>

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>spring-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

spring-dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
">
    <context:component-scan base-package="sajjad.htlo" />

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix">
            <value>/WEB-INF/</value>
        </property>

        <property name="suffix">
            <value>.jsp</value>
        </property>

    </bean>

</beans>

我的简单 Controller :

@Controller
public class HelloController {
@RequestMapping("/welcome")
protected ModelAndView handleRequestInternal(HttpServletRequest hsr, HttpServletResponse hsr1) throws Exception {
    ModelAndView model = new ModelAndView("HelloPage");
    model.addObject("msg", "hello wolrd");
    return model;
}
}

我的简单 View :

<html>
<body>
    <h1>Spring mvc web app demo</h1>

    <h2> ${msg}} </h2>

</body>

输出:

apache tomcat 控制台:

最后，当尝试http://localhost:8084/FirstSpringMVCProject/welcome时，我得到了HTTP Status 500 - Servlet.init() for servlet spring-dispatcher抛出异常 >

我的代码有什么问题吗？

最佳答案

您必须将命名空间添加到 spring-dispatcher-servlet.xml 文件中:

<?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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
">
    <context:component-scan base-package="sajjad.htlo" />

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix">
            <value>/WEB-INF/</value>
        </property>

        <property name="suffix">
            <value>.jsp</value>
        </property>

    </bean>

</beans>

最好从 xsd 文件名中删除版本号，因为这将从您的依赖项中获取实际的 xsd 版本。
