在使用XML方式配置项目,使用fastjson做为Json转换器时通常的在XML内添加如下的配置:
<mvc:message-converters register-defaults="true">
<bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
<property name="supportedMediaTypes" value="application/json"/>
<property name="features">
<array>
<value>WriteMapNullValue</value>
<value>WriteDateUseDateFormat</value>
</array>
</property>
</bean>
</mvc:message-converters>
当项目不使用XML配置而使用全注释方式时,实现WebMvcconfigurer接口并重写extendMessageConverters方法并添加fastjson转换器
@Configuration
@EnableWebMvc
@ComponentScan("com.wey.spring.controller")
public class MvcConfig implements WebMvcConfigurer { @Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/classes/views/");
viewResolver.setSuffix(".jsp");
viewResolver.setViewClass(JstlView.class);
return viewResolver;
} /**
* 使用FastJson做为json转换器
*/
public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
FastJsonHttpMessageConverter converter = new FastJsonHttpMessageConverter();
List<MediaType> mediaTypes = new ArrayList<MediaType>();
mediaTypes.add(new MediaType(MediaType.TEXT_HTML, Charset.forName("UTF-8")));
mediaTypes.add(new MediaType(MediaType.APPLICATION_JSON, Charset.forName("UTF-8")));
mediaTypes.add(new MediaType(MediaType.APPLICATION_XML, Charset.forName("UTF-8"))); converter.setSupportedMediaTypes(mediaTypes); FastJsonConfig fastJsonConfig = new FastJsonConfig();
fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); converter.setFastJsonConfig(fastJsonConfig); converters.add(converter);
}
/**
* 静态资源
*/
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**").addResourceLocations("classpath:static/");
}
}
