[Spring boot] web App returns JSP page

A colleague created a spring boot project and uploaded it to SVN. I need to write a page. After downloading, it is always impossible to configure the direct return JSP page in the controller method.

Depressed for an afternoon, finally fix the problem. Record it here.

Target: Configure the direct return JSP page in the Controller method

Add the Src/main/webapp folder to the project, nothing to say.

The different implementations of @controller annotations and @restcontroller annotations are described in detail below.

@Controller annotations

1. Configuration in the Application.properties file

# Configure the location of the JSP file, the default location is: Src/main/webapp
spring.view.prefix:/pages/  #指向jsp文件位置: src/main/webapp/pages

# Configure the suffix of the JSP file
spring.view.suffix:.jsp

2. Configuration in controller files

 import   Org.springframework.stereotype.Controller;  import   org.springframework.web.bind.annotation.RequestMapping;  import   Org.springframework.web.bind.annotation.RequestMethod; @Controller  public  class   Examplecontroller {@RequestMapping (value  = "/initpage", Method = public   String Doview () { return  "index"; //  accessible to: src/main/webapp/pages/index.jsp  }}  

3. Start with the application [main] method

4. Access the URL, access to the JSP page

http://localhost:8080/initpage

@RestController annotations

1. Configuration in the Application.properties file

# Configure the location of the JSP file, the default location is: src/main/webappspring.mvc.view.prefix:/pages/  #指向jsp文件位置: src/main/webapp/  Pages    NOTE!!!!! The property name is not the same as the @controller configuration, more "MVC" # Configure the suffix of the JSP file spring.mvc.view.suffix:.jsp # There's    just as much "mvc" Yo

2. controller file configuration, also accessible to: src/main/webapp/pages/index.jsp

Importorg.springframework.web.bind.annotation.RequestMapping;ImportOrg.springframework.web.bind.annotation.RequestMethod;ImportOrg.springframework.web.bind.annotation.RestController;ImportOrg.springframework.web.servlet.ModelAndView; @RestController Public classOvalalarmcontroller {@RequestMapping (value= "/initpage", method =requestmethod.get) PublicModelandview Doview () {Modelandview mv=NewModelandview ("Index"); returnMV; }}

3. Start with the application [main] method

4. Access the URL, access to the JSP page

Http://localhost:8080/initpage

Also encountered a problem:

Spring boot returns the JSP file download directly.

Reason:

The JSP file is not parsed, just add the following configuration in the Pom.xml file. OK, problem solved.

    <Dependency>        <groupId>Org.apache.tomcat.embed</groupId>        <Artifactid>Tomcat-embed-jasper</Artifactid>        <version>7.0.59</version>    </Dependency>
