Question

我正在尝试用春季启动制作网络应用程序，我花了很多时间，看了很多帖子和文章，但仍然无法重定向到我的jsp，我做错了什么？我有：

我的项目结构（我无法发布图片）：

application.properties：

spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp

spring.session.store-type=none

spring.datasource.url:jdbc:mysql://localhost/phonebook?useSSL=false
spring.datasource.username:root
spring.datasource.password:root
spring.datasource.driver:com.mysql.jdbc.Driver

spring.jpa.properties.hibernate.dialect:org.hibernate.dialect.MySQL5Dialect
logging.level.org.hibernate.SQl:debug

class WebMvcConfig：

@Configuration
//@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {

@Override
public void configureDefaultServletHandling(
        DefaultServletHandlerConfigurer configurer) {
    configurer.enable();
}

@Bean
public InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver resolver = new      InternalResourceViewResolver();
    resolver.setPrefix("WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    return resolver;
}

控制器：

@Controller
public class MainController {

@RequestMapping(value = "/index", method = RequestMethod.GET)
@ResponseBody
public String index() {
   return "index";
}
}

SpringBootApplication：

//@Configuration
//@ComponentScan
//@EnableAutoConfiguration
@SpringBootApplication
public class PhoneBookApplication extends SpringBootServletInitializer{

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

从我的控制器中删除@ResponseBody后，我遇到了这个例外：

There was an unexpected error (type=Internal Server Error, status=500). Error resolving template "index", template might not exist or might not be accessible by any of the configured Template Resolvers

Answer 1

您需要从控制器方法中删除@ResponseBody才能调度视图（index.jsp），否则响应将作为http正文的一部分返回。

@ResponseBody注释指示方法返回值应该受到网络响应机构的约束。

http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/bind/annotation/ResponseBody.html

Answer 2

解决您的问题：

There was an unexpected error (type=Internal Server Error, status=500). Error resolving template "index", template might not exist or might not be accessible by any of the configured Template Resolvers

尝试更改您的应用程序：

对于WebMvcConfig使用模板解析器，您不需要jsp类。您可以在application.properties文件中正确配置后缀和前缀。所以删除这个类。

@SpringBootApplication
public class PhoneBookApplication extends SpringBootServletInitializer{

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(PhoneBookApplication.class);
    }

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

控制器：

@Controller
public class MainController {

    @RequestMapping(value = "/index", method = RequestMethod.GET)
    public String index() {
       return "index";
    }
}

如果你不使用百日咳作为模板，你不需要template文件夹中的resource文件夹和pom中的依赖项。你可以删除

   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>

Answer 3

请删除此 application.properties：

spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
enter code here

此外，从控制器 @ResponseBody

中删除它

@Controller
public class MainController {

@RequestMapping(value = "/index", method = RequestMethod.GET)
public String index() {
   return "index";
}
}

Answer 4

在我的情况下，我正在使用Spring MVC API部署一个 ngular应用程序。

其他解决方案对我不起作用，所以我使用了servlet-mapping文件中的web.xml。

这是web.xml文件中Servlet及其Mappling的示例。

<servlet>
    <servlet-name>index</servlet-name>
    <jsp-file>/index.html</jsp-file>
</servlet>

<servlet-mapping>
    <servlet-name>index</servlet-name>
    <url-pattern>/login/*</url-pattern>
</servlet-mapping>

需要将web.xml文件放置在Web-INF目录中。

这是web.xml文件的结构

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app>
... Your configurations
</web-app>

Controller返回String＆＃34; index＆＃34;而不是重定向到index.jsp
