響應json去除參數值為空的參數-springboot配置

1.添加jackson相關依賴

<!--jackson 開始-->
<dependency>
 <groupId>com.fasterxml.jackson.core</groupId>
 <artifactId>jackson-core</artifactId>
 <version>${jackson.version}</version>
</dependency>
<dependency>
 <groupId>com.fasterxml.jackson.core</groupId>
 <artifactId>jackson-databind</artifactId>
 <version>${jackson.version}</version>
</dependency>
<!--jackson 結束-->

2.添加如下配置

/**

 */
@Configuration
public class JsonConfig {
 @Bean
 @Primary
 @ConditionalOnMissingBean(ObjectMapper.class)
 public ObjectMapper jacksonObjectMapper(Jackson2ObjectMapperBuilder builder){
 ObjectMapper objectMapper = builder.createXmlMapper(false).build();
 objectMapper.setSerializationInclusion(JsonInclude.Include.NON_EMPTY);
 return objectMapper;
 }
}
