思路：针对出参进行序列化处理
package com.sikaryofficial.common.security.config;
import com.fasterxml.jackson.databind.MapperFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.module.SimpleModule;
import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
@Configuration
public class JacksonConfig {
@SuppressWarnings("deprecation")
@Bean
public MappingJackson2HttpMessageConverter jackson2HttpMessageConverter() {
final Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
/**
* 序列化时，将 null 值不输出
* builder.serializationInclusion(JsonInclude.Include.NON_NULL);
*/
final ObjectMapper objectMapper = builder.build();
SimpleModule simpleModule = new SimpleModule();
// Long 转为 String 防止 js 丢失精度
simpleModule.addSerializer(Long.class, ToStringSerializer.instance);
objectMapper.registerModule(simpleModule);
// 忽略 transient 关键词属性
objectMapper.configure(MapperFeature.PROPAGATE_TRANSIENT_MARKER, true);
return new MappingJackson2HttpMessageConverter(objectMapper);
}
}
