如何使用Spring MVC 4从另一个Web项目引用静态资源

Question

How to reference static resources from another web project with Spring MVC 4. We have 2 projects one with conext root /SampleWeb and other with /SampleStatic. Sample web project is a Spring MVC 4 application that needs to access the static HTML pages from /SampleStatic project.

We tried with the below configurations for MVC resource handler but it does not work. The code is in /SampleWeb AppConfig.java file

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {

    registry.addResourceHandler("/views/**").addResourceLocations(
            "/SampleStatic/");
}

You have few alternatives. First note that your configuration is based on the Spring's Resources abstraction

in Spring MVC the prefix inside the location instructs the lookup strategy, and there are four types

classpath: - resources loaded from the classpath.
file: - resources loaded as a URL, from the filesystem.
http: - resources loaded as a URL.
(none) - depends on the underlying `ApplicationContext`

Your current config is the forth strategy. If its not working, than check how you loaded the context to learn whether the path will be relative to classpath or the relative path based on the context file system location.

My advice to you, since you're mixing the two apps, is to find the least common denominator classpath , file or http and use the prefix explicitely
