我的家

@RequestMapping(value = {"/home", "/"}, method = RequestMethod.GET)
public String showHome(Model model) {
    log.info("showHome");
    return "home";
}

是的，我在路径 src/main/webapp/WEB-INF/views 中有文件 home.jsp 我无法修复它，有人可以帮助我吗？

像这样更改您的请求映射..

@RequestMapping(value = "/home", method = RequestMethod.GET)
public String showHome(Model model) {
    log.info("showHome");
    return "home";
}

并将其添加到您的 spring-servlet.xml..

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