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.我尝试在控制器上手动将内容类型设置为text/htmlHttpServletResponse,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"%>
<!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><%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Title</title>
</body>
</html>
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.
您的控制器应该是 a 而@Controller不是 a @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，您的自定义配置根本不需要，您可以查看团队提供的Spring boot示例https://github.com/spring-projects/spring-boot/tree/master/spring-boot -samples/spring-boot-sample-web-jsp。
