Spring MVC将jsp作为text / plain内容类型返回

我遇到了Spring MVC和jsp网页的问题。

当我请求网页时,默认情况下返回 text / plain 。我尝试在HttpServletResponse控制器上手动将内容类型设置为 text / html ,然后网络浏览器重新协调它,正确显示它但是在jsp标签处编码身体。示例:

JSP:

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Error 405 ******* </title>
    </head>
    <body> asdasdsasad </body>
</html>

浏览器收到:

<html>
   <body>&lt;%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%&gt;

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Title</title>

    </body>
</html>

我使用Spring Boot和基于java web的注释进行配置。另外,我使用@EnableAutoConfiguration,我发现问题是通过映射来自&#34; / *&#34;的sevlet来解决的。到&#34; /&#34;。

由于java注释,我不得不重写dispatchedServlet(https://github.com/spring-projects/spring-boot/issues/91#issuecomment-27626036),配置类是:

@Configuration
public class DispatcherConfiguration {

@Bean
public ServletRegistrationBean dispatcherRegistration() {
    ServletRegistrationBean registration = new ServletRegistrationBean(dispatcherServlet());
    registration.addUrlMappings("/");
    registration.setLoadOnStartup(1);

    System.out.println("~~~~~~~ Servlet regristated " + registration.getServletName());
    return registration;

}

@Bean
public DispatcherServlet dispatcherServlet() {
    return new DispatcherServlet();
}

请注意,我使用@Bean注释错过了之前的注释链接,因为如果没有,则Spring引发异常。但即使不使用bean注释,并使用xml,主要问题仍然存在。)

这是Spring MVC配置文件:

@Configuration
@EnableWebMvc
@ComponentScan("es.sfacut")
public class WebMvcConfiguration extends WebMvcConfigurerAdapter {

@Override
public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/login").setViewName("login"); 
    registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
}

// Maps resources path to webapp/resources
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    registry.addResourceHandler("/images/**").addResourceLocations("/resources/images/");
    registry.addResourceHandler("/imgs/**")
        .addResourceLocations(Constant.RESOURCE_IMAGES_PATH);
}

@Bean
public UrlBasedViewResolver setupViewResolver() {
    UrlBasedViewResolver resolver = new UrlBasedViewResolver();
    resolver.setPrefix("/WEB-INF/views/");
    resolver.setSuffix(".jsp");
// resolver.setContentType("text/html");
    resolver.setViewClass(JstlView.class);

    return resolver;
}

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

@Bean
public MultipartResolver multipartResolver() {
    CommonsMultipartResolver resolver = new CommonsMultipartResolver();
    // Size in bytes
    resolver.setMaxUploadSize(1752300);
    return resolver;
}

}

主要课程:

@EnableAutoConfiguration
@ComponentScan("es.sfacut")
@EnableJpaRepositories
public class TelocomproMain {

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

}

控制器:

@RestController
@RequestMapping(value = "/api/")  
public class CategoryController {
    @RequestMapping(value="test4", method = RequestMethod.GET, produces = "text/plain;charset=UTF-8")
    public ModelAndView pageTest4(HttpServletResponse response) {

        ModelAndView model = new ModelAndView("elovendo/index");
        response.setContentType("text/html");
        response.setCharacterEncoding("UTF-8");
        return model;
    }
}

Application.properties:

#View resolver
spring.view.prefix= /WEB-INF/views/
spring.view.suffix= .jsp

不确定我是否遗漏了某些内容,我会发布您需要的所有内容。

提前谢谢。

您的控制器应该是@Controller而不是@RestController,否则响应将以您观察到的字符串形式返回。

正如评论中已经提到的,您根本不需要自定义配置,您可以查看Spring boot团队https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-web-jsp提供的示例。

有同样的问题。 当你的jsp在目录中由 ResourceHandler 处理时会发生这种情况:

 registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");

这仅适用于静态资源 - img,css,js。 你应该把你的jsp移到外面
