奇怪org.springframework.jdbc.BadSqlGrammarException

Question

所以，我在我的項目中使用Spring，用JDBC來管理數據庫部分。

當一個人試圖註冊，填寫表格後，這種方法被稱爲：

@Override 
public String addUser(Usuario user) { 
public static String SQLADDUSER="insert into users(NOMBRE, PASSWORD, EMAIL, NEWSLETTER) values=(?,?,?,?)"; 
    getJdbcTemplate().update(SQLADDUSER,new Object[]{user.getNombre(), user.getPass(), user.getEmail(),user.isNewsletter()}); 
    return "ok"; 
} 

我有一些sysouts那裏看到user.getNombre（），等等不爲空。他們有合適的價值。

我在數據庫中有一些其他模式（我正在使用MySQL），其中一個標記爲默認模式。但是，在這個應用程序的其他部分，我從用戶那裏做了select *，並且用戶很好地返回。

我這樣宣佈我的數據源豆：

<beans:bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <beans:property name="driverClassName" value="com.mysql.jdbc.Driver"></beans:property> 
    <beans:property name="url" value="jdbc:mysql://localhost:3306/theproperschema"></beans:property> 
    <beans:property name="username" value="root"></beans:property> 
    <beans:property name="password" value="root"></beans:property> 
</beans:bean> 
<beans:bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> 
    <beans:property name="dataSource" ref="dataSource"></beans:property> 
</beans:bean> 

表用戶已經4列一旁id列（主鍵）的，：農佈雷，傳遞，電子郵件（這三個是VARCHAR）和通訊（是一個二進制文件）。

而且，當我嘗試插入這個，我有這樣的例外：

Request processing failed; nested exception is org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [insert into users(NOMBRE, PASSWORD, EMAIL, NEWSLETTER) values=(?,?,?,?)]; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '=('jarl','nopuedor','tedacuen',1)' at line 1] con causa raíz

我不知道哪裏出錯。任何幫助？

Answer 1

你不需要等號=在您的SQL查詢

insert into users(NOMBRE, PASSWORD, EMAIL, NEWSLETTER) values=(?,?,?,?) 

只要寫這個代替

insert into users(NOMBRE, PASSWORD, EMAIL, NEWSLETTER) values(?,?,?,?)
