我将greeting.html文件放在src/main/webapp/web-inf/templates和src/main/resources/templates中，我试图在application.properties中指定

# For the standard MVC JSTL view resolver
spring.view.prefix=/WEB-INF/templates/
spring.view.suffix=.html

我尝试了这些StackOverflow中提出的解决方案：“Spring Boot不提供静态内容”和“Spring Boot不启动静态web内容”，但没有任何改变...

最后是WebSecurityConfigurerAdapter：

public class StatelessAuthenticationSecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
private UserDetailsService userDetailsService;

@Autowired
private TokenAuthenticationService tokenAuthenticationService;

@Autowired
private LDAPAuthenticationService ldapAuthenticationService;

@Value("${ldap.useLdapForAuthentication}")
private String useLdapForAuthentication;

public StatelessAuthenticationSecurityConfig() {
    super(true);

}

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
            .exceptionHandling().and()
            .anonymous().and()
            .servletApi().and()
            .headers().cacheControl().and()
            .authorizeRequests()

            //allow anonymous resource requests
            .antMatchers("/").permitAll()
            .antMatchers("/documentation").permitAll()
            .antMatchers("/greeting").permitAll()

            .antMatchers("/favicon.ico").permitAll()
            .antMatchers("/resources/**").permitAll()

            //allow anonymous POSTs to login
            .antMatchers(HttpMethod.OPTIONS, "/api/login").permitAll()
            .antMatchers(HttpMethod.POST, "/api/login").permitAll()
            .antMatchers(HttpMethod.OPTIONS, "/api/**").permitAll()
            .antMatchers(HttpMethod.POST, "/api/**").hasAnyRole("ADMIN", "USER")
            .antMatchers(HttpMethod.GET, "/api/**").hasAnyRole("ADMIN", "USER") //e compagnia cantando 

            //defined Admin only API area
            .antMatchers("/admin/**").hasRole("ADMIN")

            //all other request need to be authenticated
            .anyRequest().hasRole("USER")
            .and()              

            // custom JSON based authentication by POST of {"username":"<name>","password":"<password>"} which sets the token header upon authentication
            .addFilterBefore(new StatelessLoginFilter("/api/login", tokenAuthenticationService, userDetailsService, ldapAuthenticationService, authenticationManager(), useLdapForAuthentication), UsernamePasswordAuthenticationFilter.class)

            // custom Token based authentication based on the header previously given to the client
            .addFilterBefore(new StatelessAuthenticationFilter(tokenAuthenticationService), UsernamePasswordAuthenticationFilter.class);
}

@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());
}

@Override
protected UserDetailsService userDetailsService() {
    return userDetailsService;
}

@RestController
public class GreetingController {

@RequestMapping("/greeting")
public String greeting(@RequestParam(value="name", required=false, defaultValue="World") String name, Model model) {
    model.addAttribute("name", name);
    return "greeting";
}
}

根据Spring指南：构建RESTful Web服务

传统MVC控制器和上面的RESTful web服务控制器之间的一个关键区别是创建HTTP响应体的方式。这个RESTful web服务控制器不依赖视图技术来执行将问候语数据呈现到HTML的服务器端，而是简单地填充并返回一个问候语对象。对象数据将作为JSON直接写入HTTP响应。

因此，在您的示例中，它在JSON中返回“Greetines”。如果要让它返回页面greeting.html，则应该使用普通的@controller。
