我有Spring MVC和jsp网页的问题.
当我请求网页时,它默认返回text / plain.我尝试在HttpServletResponse控制器上手动将内容类型设置为text / html,并且Web浏览器重新协调它,正确显示它但是在主体上编码jsp标记.例：
JSP：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
Meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
浏览器收到：
Meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
我正在使用Spring Boot和基于java web的注释进行配置.另外,我正在使用@EnableAutoConfiguration,我发现通过将sevlet从“/ *”映射到“/”来解决问题.
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,我正在使用@Bean注释错过上一个注释链接,因为如果没有,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什么,我会发布你需要的一切.
先感谢您.
最佳答案
您的控制器应该是@Controller而不是@RestController,否则响应将作为您观察到的字符串返回.
正如评论中已经提到的那样,根本不需要您的自定义配置,您可以查看Spring启动团队https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-web-jsp提供的示例.
