新手程序员在这里。 一旦这样的tomcat MVN:运行出现以下错误:
SEVERE: Servlet.service() for servlet appServlet threw exception
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 'values (?, ?)' at line 1
有问题的代码如下:
public void create(User user) {
this.jdbcTemplate.update("INSERT INTO xyz.user(user_name, user_password values (?, ?)");
user.getUserName(); user.getId();
}
public void delete(User user) {
this.jdbcTemplate.update("DELETE FROM xyz.user WHERE id = ?");
}
public void update(User user) {
this.jdbcTemplate.update(
"UPDATE xyz.user SET UserName = ? password = ? WHERE id = ?");
Google搜索 - 无法找到一个解决方案场景(?,?)。 PLS。 帮助 - THX提前:)
下面是完整的代码(几乎) - 我做错了什么,但无法弄清楚什么。
public User find(String login) {
System.out.println("Trying to find the user...." + login);
User user = this.jdbcTemplate.queryForObject(
"select * from xyz where user_name = ?",
new Object[]{login},
new RowMapper<User>() {
public User mapRow(ResultSet rs, int rowNum) throws SQLException {
User user = new User();
user.setId(Long.valueOf(rs.getInt(1)));
user.setUserName(rs.getString(2));
user.setPassword(rs.getString(3));
return user;
}
});
System.out.println("Found user..." + user);
return user;
}
public void create(User user) {
this.jdbcTemplate.update("INSERT INTO ibstechc_dev.user(user_name, user_password) VALUES (?,?)");
user.getUserName(); user.getId() ;
}
public void delete(User user) {
this.jdbcTemplate.update("DELETE FROM xyz WHERE id = ?");
// TODO Auto-generated method stub
}
public void update(User user) {
this.jdbcTemplate.update(
"UPDATE xyz SET user_name = ?, user_password = ? WHERE id = ?");
// TODO Auto-generated method stub
}
}
我坚持同样的错误 - tomcat的:运行引发以下 -
SEVERE: Servlet.service() for servlet appServlet threw exception
