创建没有jsp（仅限html）但没有404的First Spring（没有spring boot）Web项目

Question

我正在尝试构建我的第一个Spring Web项目，但是我不想使用jsp。我只想使用rest控制器，但是我什至无法传递使用欢迎文件index.html（默认情况下为index.jsp）的第一个request（“ /”）。 我将粘贴我的文件夹结构和类。

这是我的应用程序配置类

package com.abs.sstest.security;
@Configuration
@ComponentScan
@EnableWebMvc
public class AppConfig implements WebMvcConfigurer {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
    registry.addRedirectViewController("/", "index.html");
}

public void addResourceHandlers(final ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/static/**").addResourceLocations("/static/");
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
}

这是我的Init课

package com.abs.sstest.security;

public class AppInit implements WebApplicationInitializer{

@Override
public void onStartup(ServletContext servletContext)
        throws ServletException {
    registerDispatcherServlet(servletContext);
}

private void registerDispatcherServlet(final ServletContext servletContext) {
    WebApplicationContext dispatcherContext = createContext(AppConfig.class);
    DispatcherServlet dispatcherServlet = new DispatcherServlet(dispatcherContext);
    Dynamic dispatcher = servletContext.addServlet("dispatcher", dispatcherServlet);
    dispatcher.setLoadOnStartup(1);
    dispatcher.addMapping("/");
}

private WebApplicationContext createContext(final Class<?>... annotatedClasses) {
    AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
    context.register(annotatedClasses);
    return context;
}

}

这是我的securityconfig类

package com.abs.sstest.security;

 @Configuration
 @EnableWebSecurity
 public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

@Autowired
public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
    auth.inMemoryAuthentication().withUser("bill").password("abc123").roles("USER");
    auth.inMemoryAuthentication().withUser("admin").password("root123").roles("ADMIN");
    auth.inMemoryAuthentication().withUser("dba").password("root123").roles("ADMIN","DBA");
}

protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests()
    .antMatchers("/","/home").permitAll()
    .antMatchers("/admin/**").access("hasRole('ADMIN')")
    .antMatchers("/db/**").access("hasRole('ADMIN') and hasRole('DBA')")
    .and().formLogin()
    .and().exceptionHandling().accessDeniedPage("/Access_Denied");

}

}

这是我的安全性初始化

package com.abs.sstest.security;


public class SecurityWebApplicationInitializer extends 
AbstractSecurityWebApplicationInitializer {

}

这是我的文件夹结构文件夹结构

我在多个文件夹中粘贴了index.html，因为我在阅读各种论坛时感到困惑。

编辑： 现在我更改了我的应用程序配置类

package com.abs.sstest.security;

@Configuration
@ComponentScan(basePackages = "com.abs.sstest")
@EnableWebMvc
public class AppConfig implements WebMvcConfigurer {
@Override
 public void    configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { 
        configurer.enable();
}

@Override
public void addViewControllers(ViewControllerRegistry registry) {
    registry.addRedirectViewController("/", "/index");
    registry.addRedirectViewController("/login2", "/login2");
}

public void addResourceHandlers(final ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/static/**").addResourceLocations("/static/");
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    registry.addResourceHandler("/views/**").addResourceLocations("/WEB-INF/views/");
}
}

init类现在更加简单

package com.websystique.springsecurity.configuration;

public class SpringMvcInitializer extends 
AbstractAnnotationConfigDispatcherServletInitializer {

@Override
protected Class<?>[] getRootConfigClasses() {
    return new Class[] { HelloWorldConfiguration.class };
}

@Override
protected Class<?>[] getServletConfigClasses() {
    return null;
}

@Override
protected String[] getServletMappings() {
    return new String[] { "/" };
}

}

现在主要的是，我所有的html文件都位于src / main / webapp / index.html

但是这导致了一个新问题，现在我必须从控制器返回甚至扩展名。 例如：

@RequestMapping(value = "/login2", method = RequestMethod.GET)
public String loginPage() {
    return "login.html";//login doesn't work
}

Answer 1

首先，您应该将index.html放在/ WEB_INF / view /中。 看来您需要添加ViewResolver，以便Spring知道如何解析控制器返回的字符串。因此，请尝试将其添加到您的AppConfig类中：

@Bean
public ViewResolver internalResourceViewResolver() {
    InternalResourceViewResolver bean = new InternalResourceViewResolver();
    bean.setViewClass(JstlView.class);
    bean.setPrefix("/WEB-INF/view/");
    bean.setSuffix(".html");
    return bean;
}

当然，请确保您的pom文件中有必要的依赖项！
