解决renren-security使用oracle主键问题
下载项目，直接配置oracle数据库，在配置文件中使用 id-type: ID_WORKER 模式的主键生成策略，但是出现了错误
错误描述为：前端的Long类型主键最后位数精度不对，变成了00
解决方法在项目新增如下代码,方式是将返回的Long 类型的id以字符串的方式返回

package io.renren.common.config;
import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;
@Configuration
public class JacksonConfig {
/**
* Jackson全局转化long类型为String，解决jackson序列化时long类型缺失精度问题
* @return Jackson2ObjectMapperBuilderCustomizer 注入的对象
*/
@Bean
public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
Jackson2ObjectMapperBuilderCustomizer cunstomizer = new Jackson2ObjectMapperBuilderCustomizer() {
@Override
public void customize(Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) {
jacksonObjectMapperBuilder.serializerByType(Long.class, ToStringSerializer.instance)
.serializerByType(Long.TYPE, ToStringSerializer.instance);
}
};
return cunstomizer;
}
}
