無法在Spring Boot MVC中解析視圖名稱

Question

我正在使用spring boot開發spring MVC應用程序。

我的pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
    <optional>true</optional>
</dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <!-- <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency> -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <!-- <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-test</artifactId>
        <scope>test</scope>
    </dependency> -->
    <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-core -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-c3p0</artifactId>
</dependency>
    <!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
    <dependency>
        <groupId>com.google.guava</groupId>
        <artifactId>guava</artifactId>
        <version>19.0</version>
    </dependency>

和我的控制器類：

@EnableWebMvc
@Controller
public class RootController {
@RequestMapping("/")
public String home()

{
    return "index";
}

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

應用類

@SpringBootApplication
@ComponentScan(basePackages= {"com.approot.controller"})
@EnableWebMvc
public class LimitBoApplication {

public static void main(String[] args) {
    SpringApplication.run(LimitBoApplication.class, args);
}

}

我的春季application.properties

server.port =8090
spring.mvc.view.suffix=.jsp
server.servlet.context-path=/AppBO

當我運行此應用程序時，出現以下錯誤。

   Could not resolve view with name 'index' in servlet with name 
  'dispatcherServlet'
   javax.servlet.ServletException: Could not resolve view with name 'index' 
   in servlet with name 'dispatcherServlet'
   at org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1350)
   at org.springframework.web.servlet.DispatcherServlet.processDispatchResult(DispatcherServlet.java:1116)
   at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:1055)
   at  org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:942)

我已經將我的jsp文件放在LimitBO\\src\\main\\resources\\templates ，spring仍然找不到jsp文件。

我在這里做錯了什么？ 我試圖將這些jsp文件添加到recources文件夾中，但仍然無法正常工作。

Answer 1

將您.jsp文件src/main/webapp/WEB-INF/jsp/並添加spring.mvc.view.prefix: /WEB-INF/jsp/到application.properties ，你不需要@EnableWebMvc在RootController 。

希望這可以幫助。

Answer 2

創建Java配置並嘗試以下操作：

@Configuration
@EnableWebMvc
public class WebConfigMvc extends WebMvcConfigurerAdapter {

    @Bean
    public ViewResolver viewResolver () {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/jsp"); //this is location you put jsp
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }
}

通過JSP渲染tomcat時，您需要添加dependecy。

    <!-- Tomcat for JSP rendering -->
  <dependency>
     <groupId>org.apache.tomcat.embed</groupId>
     <artifactId>tomcat-embed-jasper</artifactId>
     <scope>provided</scope>
    </dependency>

如果配置不起作用。 嘗試以下：

 spring.mvc.view.prefix = /WEB-INF/jsp/
   spring.mvc.view.suffix = .jsp
   spring.mvc.static-path-pattern=/resources/**
