org.springframework.dao.TransientDataAccessResourceException: PreparedStatementCallback; SQL [select * from test01 where id = ]; Parameter index out of range (1 > number of parameters, which is 0).; nested exception is java.sql.SQLException: Parameter index out of range (1 > number of parameters, which is 0).
Caused by: java.sql.SQLException: Parameter index out of range (1 > number of parameters, which is 0).
一般情况下这是因为sql语句的错误，没有输入要查询的范围也就是对应的id值。所有才报了超出发索引范围的错误。
解决办法
String sql = “select * from test01 where id = ？”;
这个 ？号很关键
