在Spring Boot中混合thymeleaf和jsp文件

有没有使用普通的jsp文件,而没有控制器与使用Spring Boot / MVC中的控制器的百万美元视图混合?

例如,标准控制器如下;

@RequestMapping("/")
public String get() {
    return "view";
}

哪个工作完全符合预期,但是可以将放在文件夹中的“.jsp”文件映射到任何网址,例如test.jsp将转到www.website.com/test.jsp

问候。

我在servlet-context.xml中使用以下配置(DispatcherServlet的contextConfigLocation):

<!-- Resolves views selected for rendering by @Controllers to .jsp resources 
    in the /WEB-INF/views directory -->
<beans:bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <beans:property name="prefix" value="/WEB-INF/views/" />
    <beans:property name="suffix" value=".jsp" />
    <beans:property name="viewNames" value="jsp/*"></beans:property>
    <beans:property name="order" value="1"></beans:property>
</beans:bean>

<!-- Thymeleaf -->
<beans:bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
    <beans:property name="templateEngine" ref="templateEngine" />
    <!-- This narrows the scope of the resolver to the view names (returned 
        by the controllers' methods) to those matching the pattern -->
    <beans:property name="viewNames" value="templates/*"></beans:property>
    <!-- places this resolver before the default InternalResourceViewResolver -->
    <beans:property name="order" value="0"></beans:property>
</beans:bean>

<beans:bean id="templateResolver"
    class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
    <beans:property name="prefix" value="/WEB-INF/views/" />
    <beans:property name="templateMode" value="HTML5" />
    <beans:property name="suffix" value=".html" />
</beans:bean>

<beans:bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine">
    <beans:property name="templateResolver" ref="templateResolver" />
</beans:bean>

<!-- Thymeleaf _ end -->

为了使用JSP呈现响应,在控制器中我返回如下字符串:

@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {

    return "jsp/home";
}

然后使用百日咳模板进行渲染,我会执行以下操作:

@RequestMapping(value = "/", method = RequestMethod.GET)
public String getRanks(Model model, HttpServletRequest request)
{
    return "templates/user/ranks";
}

当然,.jsp.html文件的物理位置必须与控制器返回的视图名称匹配。因此,根据解析器的配置方式,您必须将.jsp/views/jsp文件放在.html

内的/views/templateswww.website.com/test.jsp文件中

如果您希望使用test.jsp视图呈现web.xml之类的网址,则只需将aformentiond jsp文件放在网络应用的根目录中即可。如果没有奇怪的配置,则应该由JSP servlet解析该请求。实际上,像Tomcat这样的servlet容器通常在其全局<servlet> <servlet-name>jsp</servlet-name> <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class> <init-param> <param-name>fork</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>xpoweredBy</param-name> <param-value>false</param-value> </init-param> <load-on-startup>3</load-on-startup> </servlet> 文件中具有此规范:

<!-- The mappings for the JSP servlet -->
<servlet-mapping>
    <servlet-name>jsp</servlet-name>
    <url-pattern>*.jsp</url-pattern>
    <url-pattern>*.jspx</url-pattern>
</servlet-mapping>

return $http.get(...)

如果您想要更具个性化和特定性的内容,则必须相应地修改配置。例如,从servlet容器的web.xml中删除JSP servlet,并在适当的控制器中映射* .jsp url
