Salve, salve pessoal se voc\u00ea est\u00e1 trabalhando com Spring MVC<\/strong> e se deparou com a exception org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation<\/strong> este artigo visa ajudar a resolver este problema.
\nIsso se deve ao fato do HttpMessageConverter<\/strong> n\u00e3o estar configurado ou configurado com erros. A solu\u00e7\u00e3o \u00e9 editar sua classe de configura\u00e7\u00f5es WebMvcConfig<\/strong> adicionando dois converters ResourceHttpMessageConverter<\/strong> e MappingJackson2HttpMessageConverter<\/strong>. Isso \u00e9 bastante simples e basta que voc\u00ea adicione o trecho de c\u00f3digo abaixo:<\/p>\n

\n\n    @Override\n    public void configureMessageConverters(List<httpmessageconverter<?>&gt; converters) {\n    \tconverters.add(converterResourceHttpMessageConverter());\n        converters.add(converterJackson2Http());\n        super.configureMessageConverters(converters);\n    }\n\n    @Bean\n    public MappingJackson2HttpMessageConverter converterJackson2Http() {\n    \tMappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();\n    \t\/\/do your customizations here...\n    \treturn converter;\n    }\n\n    @Bean\n    public ResourceHttpMessageConverter converterResourceHttpMessageConverter() {\n    \tResourceHttpMessageConverter converter = new ResourceHttpMessageConverter();\n    \t\/\/do your customizations here...\n    \treturn converter;\n    }\n\n<\/pre>\n
Bom mas pode ser que voc\u00ea se depare ainda com a exception java.lang.ClassNotFoundException: org.codehaus.jackson.JsonProcessingException<\/strong>. E a solu\u00e7\u00e3o tamb\u00e9m \u00e9 simples, certifique se de que as depend\u00eancias jackson-core-asl<\/strong>, jackson-mapper-asl<\/strong> e jackson-jaxrs-xml-provider<\/strong> estejam adicionadas ao projeto, caso n\u00e3o estejam adicionem. Para quem usa Maven eu vou facilitar ainda mais as coisas, basta adicionar esse trecho de c\u00f3digo ao seu pom.xml e ser feliz, para os demais \u00e9 s\u00f3 sair catando jar na pata.<\/p>\n
\n\n\t<dependency>\n\t\t<groupid>org.codehaus.jackson<\/groupid>\n\t\t<artifactid>jackson-core-asl<\/artifactid>\n\t\t<version>XYZ<\/version>\n\t<\/dependency>\n\t<dependency>\n\t\t<groupid>org.codehaus.jackson<\/groupid>\n\t\t<artifactid>jackson-mapper-asl<\/artifactid>\n\t\t<version>XYZ<\/version>\n\t<\/dependency>\n\t<dependency>\n\t\t<groupid>com.fasterxml.jackson.jaxrs<\/groupid>\n\t\t<artifactid>jackson-jaxrs-xml-provider<\/artifactid>\n\t\t<version>XYZ<\/version>\n\t<\/dependency>\n\n<\/pre>\n
Feito isto \u00e9 s\u00f3 inicializar novamente o projeto que as coisas ir\u00e3o funcionar.<\/p>\n
