当不使用 Jackson 时，Spring 将默认 Content-type 设置为“application/json;charset=utf-8”

Question

我想将我的 spring 应用程序默认“内容类型”更改为“application/json;charset=utf-8”，而不仅仅是“application/json”

Answer 1

弹簧 > 4.3.4

@RequestMapping(produces = MediaType.APPLICATION_JSON_UTF8_VALUE)

Answer 2

@Configuration
@EnableWebMvc
public class MVCConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureContentNegotiation(
         ContentNegotiationConfigurer configurer) {
        final Map<String, String> parameterMap = new HashMap<String, String>();
        parameterMap.put("charset", "utf-8");

        configurer.defaultContentType(new MediaType(
          MediaType.APPLICATION_JSON, parameterMap));
    }
}

Answer 3

修改产生

例如：

@RequestMapping(method = RequestMethod.GET, produces = { "application/json; charset=utf-8" })

public @ResponseBody Object get1() {
...
}

Answer 4

我发现的默认内容类型字符集的最简单解决方案是使用请求过滤器：

@Component
public class CharsetRequestFilter extends OncePerRequestFilter {

    @Override
    protected void doFilterInternal(HttpServletRequest request,
                                    HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        response.setCharacterEncoding("UTF-8");

        filterChain.doFilter(request, response);
    }
}
