如何使用MyBatis將Spring unicode插入到Oracle NVARCHAR

INSERT INTO rbp_users 
     (user_id, user_name, passwd, bank_id, descr, stat, p_exp, user_type_id, email_address) 
    VALUES 
     (rbp_userid_seq.NEXTVAL , 
     'any_user_name', 
     'some_encrypted_password', 
     1, 
     N'əəııööğğşşççüü', --unicode string 
     'E', 
     SYSDATE, 
     2, 
     NULL);

上面插入到帶有NVARCHAR字段「descr」的Oracle表中通過PL/SQL Developer工作正常。但我不能在MyBatis的DAO XML映射的Unicode場之前寫的「N」：如何使用MyBatis將Spring unicode插入到Oracle NVARCHAR

<insert id="addUser" parameterType="User" flushCache="true"> 
    INSERT INTO rbp_users 
     (user_id, user_name, passwd, bank_id, descr, stat, p_exp, user_type_id, email_address) 
    VALUES 
     (rbp_userid_seq.NEXTVAL , 
     #{userName,   javaType=String,  jdbcType=VARCHAR}, 
     pswcode(#{password, javaType=String,  jdbcType=VARCHAR}), 
     #{bankId,    javaType=Integer, jdbcType=NUMERIC}, 
     N#{description,   javaType=String,  jdbcType=NVARCHAR}, 
     #{userStatus,   javaType=String,  jdbcType=VARCHAR}, 
     #{passwordExpireDate, javaType=Date,  jdbcType=DATE}, 
     #{userTypeId,   javaType=Integer, jdbcType=NUMERIC}, 
     #{emailAddress,  javaType=String,  jdbcType=VARCHAR}) 

    <selectKey resultType="java.lang.Integer" keyProperty="userId"> 
     SELECT rbp_userid_seq.currval from dual 
    </selectKey> 
</insert>

這引發和錯誤：

如果從「N＃{描述，java類型消除「N」 =字符串，jdbcType爲NVARCHAR}，」也不例外加註，但插入的字符串被損壞。

我可以用下面的參數執行Tomcat的安裝後問題：

-Doracle.jdbc.defaultNChar=true 
-Doracle.jdbc.defaultNChar=true

謝謝，這個作品！這使得普通的JDBC寫的Unicode到NVARCHAR領域。此外，要做到與Hibernate同樣的事情，設定Hibernate屬性「hibernate.use_nationalized_character_data」爲真。 – Greg

我不認爲你必須在XML中的unicode字段之前提到「N」，因爲你在提到它的jdbcType。

在某些環境中，系統默認的編碼不與XML文件的青睞unicode編碼發揮出色。如果您遇到編碼問題解析與閱讀器爲輸入iBATIS的XML文件時，您可以更改默認的編碼相匹配的XML文件的編碼。例如：

String resource = 「properties/sqlMap-config.xml」; 
Resources.setCharset(Charset.forName('UTF-8」)); // change the default encoding 
Reader reader = Resources.getResourceAsReader(resource); 
SqlMapClient sqlMap = SqlMapClientBuilder.buildSqlMap(reader);

的「setCharset」的方法將改變用於以後的所有編碼調用「getResourceAsReader」。
