Afficher une image externe à l'application

Bonjour

Je souhaiterai afficher dans ma page jsp, une image qui se trouve dans un répertoire externe à l'application, c'est à dire dans C:\Users\user\test par exemple.

Voici ce que j'ai fait mais mon image ne s'affiche pas:

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

package com.clinique.config;     import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;     public class MvcConfig implements WebMvcConfigurer { public static String uploadDirectory= System.getProperty("user.home") + "\\test";   @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { registry.addResourceHandler("/test/**").addResourceLocations("file:" + uploadDirectory+"\\"); } }

---

Dans la jsp:

Code:

---

<img src="/test/000111.jpg" alt="Image 11" width="500px ">

---

L'image se trouve dans C:\Users\user\test mais elle ne s'affiche pas.

J'ai pris pour référence ce tuto: http://mkaroune.e-monsite.com/pages/...r-on-disk.html

Merci

J'ai oublié d'ajouter l'annotation @configuration au niveau de la Class MvcConfig:

Code:

---

1 2 3

@configuration public class MvcConfig implements WebMvcConfigurer

---

Cependant, lorsque j'exécute l'application, j'ai le message d'erreur suivant:

On dirait qu'il y a un conflit entre la Class MvcConfig et spring security:

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

@Configuration public class SecurityConfiguration extends WebSecurityConfigurerAdapter{ @Autowired public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication() .passwordEncoder(NoOpPasswordEncoder.getInstance()) .withUser("admin").password("ad") .roles("USER", "ADMIN"); }   @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests().antMatchers("/login", "/h2-console/**").permitAll() .antMatchers("/", "/*todo*/**").access("hasRole('USER')").and() .formLogin();   http.csrf().disable(); http.headers().frameOptions().disable(); } }

---

Bonjour,

Il faut ajouter les annotations suivantes:

Code:

---

1 2 3 4 5 6

@EnableWebMvc @Configuration @ComponentScan(basePackages = { "com.xxx.xxx" })//pas obligatoire public class WebConfig implements WebMvcConfigurer { // ... }

---

Ok mais quand j'ajoute @EnableWebMvc, j'ai ce message d'erreur:

Voici ma Class SecurityConfiguration:

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

@Configuration public class SecurityConfiguration extends WebSecurityConfigurerAdapter{ @Autowired public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication() .passwordEncoder(NoOpPasswordEncoder.getInstance()) .withUser("admin").password("ad") .roles("USER", "ADMIN"); }   @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests().antMatchers("/login", "/h2-console/**").permitAll() .antMatchers("/", "/*todo*/**").access("hasRole('USER')").and() .formLogin();   http.csrf().disable(); http.headers().frameOptions().disable(); } }

Apparemment il y a un bug avec @EnableWebMvc et WebMvcConfigurationSupport

https://dzone.com/articles/spring-bo...mmon-use-cases

J'ai donc supprimé les 2 annotations. Ensuite j'ai remarqué que j'avais fait une erreur au niveau du chemin du fichier; il fallait faire ceci:

Citation:

---

*(For Windows users: The argument passed to addResourceLocations for this example would be “file:///C:/opt/files/“).

---

Donc

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12

@Configuration public class WebConfigurer implements WebMvcConfigurer { //private static String UPLOAD_DIR = "D:\\upload";     @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { registry .addResourceHandler("/files/**") .addResourceLocations("file:///D:/upload/"); } }
