Springboot 默认的json处理方式 Jackson

Springboot 处理返回参数的设置问题,接上篇SpringBoot 整合 fastjson

配置文件

 package com.summer.isnow.config; import com.fasterxml.jackson.core.JsonGenerator; import com.fasterxml.jackson.databind.JsonSerializer; import com.fasterxml.jackson.databind.ObjectMapper; import com.fasterxml.jackson.databind.SerializerProvider; import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Primary; import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder; import java.io.IOException; /** * @author liudongting * @date 2019/8/9 10:29 */ @Configuration public class JacksonConfig { @Bean @Primary @ConditionalOnMissingBean(ObjectMapper.class) public ObjectMapper jacksonObjectMapper(Jackson2ObjectMapperBuilder builder) { ObjectMapper objectMapper = builder.createXmlMapper(false).build(); objectMapper.getSerializerProvider().setNullValueSerializer(new JsonSerializer<Object>() { @Override public void serialize(Object o, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException { jsonGenerator.writeString(""); } }); return objectMapper; } }

实体类

 @JsonView(value = View.Base.class ) private Map<String,String> map; @JsonView(value = View.Base.class ) private String [] ss; @JsonView(value = View.Base.class ) private int [] intDemo; @JsonView(value = View.Base.class ) private Integer b =null; @JsonView(value = View.Base.class ) private boolean bbbb ; @JsonView(value = View.Base.class ) private List<String> dd;

返回结果
