java - 如何使用maven多模块springboot告诉spring从自定义目录加载资源

Question

我尝试构建一个 Maven 多模块 Web 项目:

项目 A，项目 B，...

B依赖于A

运行项目B，显示的控制台比/hello映射了，但是检查localhost时找不到hello.jsp: 8080/你好

这是我的问题:

1. 运行项目B时我是如何使用hello.jsp(A中的资源)的？

2. 如何告诉spring从目录src/main/resources/加载资源？

结构A/B

A/B
|_src
|  |_main
|  |   |_java
|  |   |  |_com.x
|  |   |  |  |_AStarter.java/BStarter.java 
|  |   |  |_com.x.domain
|  |   |  |_com.x.services
|  |   |  |_com.x.web
|  |   |     |_HelloController.java/FooController.java
|  |   |_resources
|  |      |_application.properties
|  |      |_templates
|  |         |_hello.jsp
|  |_test
|      |_java
|      |_resources
|_pom.xml  

(A)pom.xml 是一个简单的类似 spring-boot 的文件。 (B)pom.xml 与 (A)pom.xml 类似，只是添加一个依赖项:

<dependency>
    <groupId>X</groupId>
    <artifactId>A</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

应用程序属性: spring.view.后缀:.jsp

更新

入门:

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class AStarter extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(
            SpringApplicationBuilder application) {
        return application.sources(AStarter.class);
     }
    public static void run(Class<? extends AStarter> c, String[] args) {
        SpringApplication.run(c, args);
    }
    public static void main(String[] args) throws Exception {
        run(AStarter.class, args);
    }
}

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class BStarter extends AStarter {
    public static void main(String[] args) {
        AStarter.run(BStarter.class, args);
    }
}

Controller :

@Controller
public class HelloController {
    private String message = "Hello World";
    @RequestMapping("/hello")
    public String welcome(Map<String, Object> model) {
        model.put("time", new Date());
        model.put("message", this.message);
        return "hello";
    }
}

@Controller
public class FooController {
    @RequestMapping("/foo")
    public String foo(Map<String, Object> model) {
        model.put("foo", "foo!");
        return "foo";
    }
}

控制台:

--- {main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/foo],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String com.x.FooController.foo(java.util.Map<java.lang.String, java.lang.Object>)
--- [main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/hello],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String com.x.web.HelloController.welcome(java.util.Map<java.lang.String, java.lang.Object>)
--- [main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/error],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)
--- [main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/error],methods=[],params=[],headers=[],consumes=[],produces=[text/html],custom=[]}" onto public org.springframework.web.servlet.ModelAndView org.springframework.boot.autoconfigure.web.BasicErrorController.errorHtml(javax.servlet.http.HttpServletRequest)

当我检查 localhost:8080/hello 时，出现错误

提前致谢!

不要将 WEB-INF 与 Spring 应用程序一起使用；它总是很脆弱，Spring 可以在类路径上的 jar 中查找。将文件放入 src/main/resources/templates 中，并且不要指定任何 spring.view.prefix。
