java – Spring-Jersey:如何返回静态内容?
作者:互联网
题 :
>如何公开我的css /,images /,js /和其他静态文件?
>如何在我的索引视图中为控制器(不是String方法)返回JSP页面?

解决方法:
“How do I expose my css/, images/, js/ and other static files?”
jersey.config.servlet.filter.staticContentRegex属性应该可以使用,但是您需要为要提供的所有类型的文件指定所有可能的模式.更简单的方法是使用属性jersey.config.servlet.filter.forwardOn404,如this answer中所述.对于这两个选项都是如此,您需要将Jersey配置为过滤器,而不是servlet.所以你的web.xml可能看起来像
<filter>
<filter-name>Jersey</filter-name>
<filter-class>org.glassfish.jersey.servlet.ServletContainer</filter-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>com.component.ResourceRegister</param-value>
</init-param>
<!-- pass to next filter if Jersey/App returns 404 -->
<init-param>
<param-name>jersey.config.servlet.filter.forwardOn404</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<url-pattern>/*</url-pattern>
<filter-name>Jersey</filter-name>
</filter-mapping>
“How do I return a JSP page in my controller (not a String method) for my index view?”
首先你需要的是jsp mvc依赖
<dependency>
<groupId>org.glassfish.jersey.ext</groupId>
<artifactId>jersey-mvc-jsp</artifactId>
<version>2.25</version>
</dependency>
然后,您需要注册该功能
public ResourceRegister () {
...
register(JspMvcFeature.class);
}
然后,您需要为所有jsp页面指定模板基本路径.例如,我使用/ WEB-INF / jsp
public ResourceRegister () {
...
property(JspMvcFeature.TEMPLATE_BASE_PATH, "/WEB-INF/jsp");
}
因此,对于这种情况,所有jsp文件都应位于/ WEB-INF / jsp目录中.
示例jsp和控制器
的index.jsp
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>JSP Page</title>
<link href="css/styles.css" rel="stylesheet">
</head>
<body>
<h1>${it.hello} ${it.world}</h1>
</body>
</html>
调节器
@Path("/")
public class HomeController {
@GET
@Produces(MediaType.TEXT_HTML)
public Viewable index() {
Map<String, String> model = new HashMap<>();
model.put("hello", "Hello");
model.put("world", "World");
return new Viewable("/index", model);
}
}
public ResourceRegister () {
...
register(HomeController.class);
}
这里,Viewable中的/ index指向index.jsp(我们不需要.jsp扩展名). Jersey知道如何从我们上面设置的属性中查找文件.
