JS &VUE前端处理Long类型丢失精度，所以

丢失精度之后

1247483477192515600

真正的数据库数值

解决办法，String--<>---Long 相互替换

@Component
@Lazy(true)
public class DozerGenerator implements IDozerGenerator {

    @Autowired
    protected Mapper dozerMapper;

    @Override
    public <T, S> T convert(S s, Class<T> clz) {
        if (null == s) {
            return null;
        }
        return dozerMapper.map(s, clz);
    }

通过属性名称复制，跳过属性类型，可以复制，不会丢失精度

package org.dozer;

public interface Mapper {
    <T> T map(Object var1, Class<T> var2) throws MappingException;

    void map(Object var1, Object var2) throws MappingException;

    <T> T map(Object var1, Class<T> var2, String var3) throws MappingException;

    void map(Object var1, Object var2, String var3) throws MappingException;
}
