（新方法）使用Java Config

扩展WebMvcConfigurerAdapter或如果需要更多控件使用WebMvcConfigurationSupport。

@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(createGsonHttpMessageConverter());
        super.configureMessageConverters(converters);
    }

    private GsonHttpMessageConverter createGsonHttpMessageConverter() {
        Gson gson = new GsonBuilder()
                .excludeFieldsWithoutExposeAnnotation()
                .setDateFormat("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'SSS'Z'")
                .create();

        GsonHttpMessageConverter gsonConverter = new GsonHttpMessageConverter();
        gsonConverter.setGson(gson);

        return gsonConverter;
    }

}

（旧方法）使用XML配置

在DispatcherServlet上下文中：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
