Thrift--JavaServer&PythonClient遇到的问题

Contact.thrift

namespace java thrift.service  
  
struct Book{
	1:i32 id
	2:string name
}

struct Contact{  
	1:i32 id  
	2:string name  
	3:i64 birthday  
	4:string phoneNo  
	5:string ipAddress  
	6:map<string,string> props  
	7:double salary
	8:set<Book> books
   
}  
  
service ContactManager{  
	void save(1:Contact contact)  
	void remove(1:i32 id)  
	list<Contact> getAll();  
	list<Contact> query(1:map<string,string> conditions)  
}  

生成java文件：

thrift  --gen java Contact.thrift

 生成python文件：

thrift  --gen py Contact.thrift

        transport.close()
    except Thrift.TException, tx:
        print '%s' % (tx.message)

    hiveExe()

问题：

这里，客户端调用query()方法，会正常得到输出：

[Contact(salary=1.900218491772795e-109, name='\xe8\xb6\x85\xe4\xba\xba', birthday=100000000, books=None, props=None, ipAddress='192.168.0.101', id=101, phoneNo='13312345678'), Contact(salary=-5.965150887436158e+213, name='\xe8\xb6\x85\xe4\xba\xba2', birthday=200000000, books=None, props=None, ipAddress='192.168.0.102', id=101, phoneNo='13312345672')]

但是，如果客户端调用getAll()方法会抛异常，TypeError: unhashable instance，提示类型不能转换，所以形如：

[Contact(id:101, name:超人, birthday:100000000, phoneNo:13312345678, ipAddress:192.168.0.101, props:null, salary:98456.36, books:[Book(id:11, name:水浒传), Book(id:10, name:西游记)])]

这样复杂的数据类型，python并不支持。
