我看到了所有与spring world有关的问题，但是在这个特殊的情况下，两者都帮不了我(I am using annotation way )

我的结构很简单：

​

​

这些是我的配置文件：

web.xml

代码语言：javascript
运行
复制
<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

代码语言：javascript
运行
复制
<?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>

我的简单控制器：

代码语言：javascript
运行
复制
@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

代码语言：javascript
运行
复制
<html>
<body>
    <h1>Spring mvc web app demo</h1>

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

</body>

​

输出：

apache tomcat console

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

代码语言：javascript
运行
复制
<?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，因为这将从依赖项中获取实际的xsd版本。

你加了一个额外的括号。

您的简单观点应该是：

在web.xml中更改url-模式，如下所示。

代码语言：javascript
运行
复制
<url-pattern>/*</url-pattern>

并在spring配置文件中声明下面一行。

代码语言：javascript
运行
复制
<context:component-scan base-package="your_base_package_name" />

您还必须在xml配置文件中添加名称空间，如下所示。

代码语言：javascript
运行
复制
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
