PowerInter
@Repository("powerInter")
public class PowerInter {
private static final Logger log = LoggerFactory.getLogger (PowerInter.class);
@Resource(name="jdbcTemplate" )
private JdbcTemplate JDBC;

 /**
 * @return the jDBC
 */
public JdbcTemplate getJDBC() {
return JDBC;
}
/**
 * @param jDBC the jDBC to set
 */
public void setJDBC(JdbcTemplate jDBC) {
System.out.println( "++++++++++++++++++authority_name1111++++++++++++++++++++++++++++" );
JDBC = jDBC;
}
public PowerInter(){

super();
JDBC=null;
 
}
public PowerInter(JdbcTemplate JDBC){
super();
 this.JDBC=JDBC;
 }
public List<String> findByTSysPowersystem() {
// TODO Auto-generated method stub

System.out.println( "++++++++++++++++++authority_name++++++++++++++++++++++++++++" );

System.out.println( "++++++++++++++++++hell++++++++++++++++++++++++++++" );
List<String> query = JDBC.query("select authority_name from Pub_authorities ",new RowMapper<String>(){ public String mapRow(ResultSet rs, int arg1) throws SQLException {

}

});
return  query;
}
public List<String> findByAutAllresource_string(String auth) {
// TODO Auto-generated method stub

List<String> query = JDBC.query("sselect resource_string " +
"from Pub_Authorities_Resources,Pub_Resources,  Pub_authorities " +

Answer 3

 public PowerInter(){
         
        super();
        JDBC=null;
      
        }改为
 public PowerInter(){
         
      
        }无参构造函数，不要写函数体

Answer 4

试了不是这个问题 ，我怀疑是不是spring security3 问题  使用了 spring security 就不能使用注解了？
