ssh下设置外键后生成hibernate的Set

Question

本来我的sql表是没设置外键的，运行正常。后来设置了外键，关联了几个表再来生成一次hibernate，改动自己的相关文件后就发生了下面的错误。
帮帮忙哈，小弟在此谢过了。。
hibernate生成的类：package com.file.vo;import java.util.Date;
import java.util.HashSet;
import java.util.Set;/**

} public String getBuildMan() {
return this.buildMan;
} public void setBuildMan(String buildMan) {
this.buildMan = buildMan;
} public Date getBuildDate() {
return this.buildDate;
} public void setBuildDate(Date buildDate) {
this.buildDate = buildDate;
} public Set<Object> getLongHealthProblems() {
return this.longHealthProblems;
} public void setLongHealthProblems(Set<Object> longHealthProblems) {
this.longHealthProblems = longHealthProblems;
} public Set<Object> getNameNumbers() {

return this.personBasicInformations;
} public void setPersonBasicInformations(Set<Object> personBasicInformations) {
this.personBasicInformations = personBasicInformations;
}}
本来应该是Set的，IDE报警告，把它们都改为Set<Object>..
找过网上的资料说是eclipse版本问题，但是实在不知道该怎么弄。给位大虾帮帮忙哈、、、

 com.file.vo.LongHealthProblem 你的MAPPING file里有没有这个映射到这个文件？
如果你是用的hibernate的工具自动生成的JAVA BEAN应该不会出现这种问题的
