我正在使用带有gradle build和thymeleaf的SpringBoot。我想将图像插入到html文件中。我想插入一张图片(/images/anabada.jpeg)我想我已经为百里香做了正确的
上面是我的html代码，下面是用于插入图片的代码，这是上述完整代码的一部分。<!DOCTYPE html>

我的项目文件夹路径。 <img th:src="@{/images/anabada.jpeg}" class="img-responsive center-block" width="300" height="300" alt="Logo" />

最佳答案
给定密码编码器后，您似乎已(或希望)启用了安全性:
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
@NoArgsConstructor @Log4j2
public class WebSecurityConfigurerImpl extends WebSecurityConfigurerAdapter {
@Autowired private UserDetailsService userDetailsService;
@Autowired private PasswordEncoder passwordEncoder;
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService)
.passwordEncoder(passwordEncoder);
}
@Override
public void configure(WebSecurity web) {
web.ignoring()
.antMatchers("/css/**", "/js/**", "/images/**",
"/webjars/**", "/webjarsjs");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests().anyRequest().permitAll()
.and().formLogin().loginPage("/login").permitAll()
.and().logout().permitAll();
}
}
关于java - 通过使用<img th:src = “@{/images/anabada.jpeg}”无法加载thyemleaf中的图像，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/62799739/
