响应json去除参数值为空的参数-springboot配置

1.添加jackson相关依赖

<!--jackson 开始-->
<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 结束-->

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;
    }
}
