根据控制台，提示的抛出异常原因，是因为 没有“com.fasterxml.jackson.databind”类型的合格bean。加载ObjectMapper类时，在候选对象中发现多个带@Primary的ObjectMapper，ObjectMapper为Jackson-databind类库的bean,
问题代码
/**
* 序列化，处理前端long 18位精确度失去问题(前端用String类型的雪花ID保持精度，后端及数据库继续使用Long(BigINT)类型不影响数据库查询执行效率。)
* @description
* @author tarzan Liu
* @version 1.0.0
* @date 2020/12/2
*/
@Configuration
public class JacksonConfig {
@Bean
@Primary
@ConditionalOnMissingBean(ObjectMapper.class)
public ObjectMapper jacksonObjectMapper(Jackson2ObjectMapperBuilder builder)
{
ObjectMapper objectMapper = builder.createXmlMapper(false).build();
// 全局配置序列化返回 JSON 处理
SimpleModule simpleModule = new SimpleModule();
//JSON Long ==> String
simpleModule.addSerializer(Long.class, ToStringSerializer.instance);
objectMapper.registerModule(simpleModule);
return objectMapper;
}
}
解决办法，因为项目中引用到第三方jar，第三方jar 里可以也有对ObjectMapper使用@Primary，造成冲突，去掉代码中的@Primary解决异常
