Druid query can query the database, found out wrong, I don't feel like gibberish, but don'-CodePudding

The servlet code:
Protected void doGet (it request, HttpServletResponse response) throws ServletException, IOException {
//TODO Auto - generated method stub
//response. GetWriter (). Append (" Served at: "), append (request) getContextPath ());
UserDaoImpl dao=new UserDaoImpl ();
List User=dao. The.findall ();
System.out.println(user);
}

The dao code:
Public class UserDaoImpl {

Private=new JdbcTemplate JdbcTemplate JDBC (DruidUtil getDataSource ());
Public List The.findall () {
//TODO Auto - generated method stub

String SQL="select * from user1";
List The users=JDBC query (SQL, new BeanPropertyRowMapper (Login. Class));
return users;
}

}

Domain code:
Public class Login {

private String name;
private String password;
Public String getName () {
return name;
}
Public void elegantly-named setName (String name) {
this.name=name;
}
Public String getPassword () {
Return the password;
}
Public void setPassword (String password) {
this.password=password;
}

}

Results query out is this:
[jdbctest. Login @ 1 b84aa37 jdbctest. Login @ 560 f9a1b jdbctest. Login @ 79 e7f97e]
I don't know is what thing,

Query out the right should be like this:
[Login [name=zhangsan, password=123], the Login [name=zhang SAN, password=123], the Login [name=lisi, password=123]]

Please bosses to help have a look at it, really desperate, I don't know why

CodePudding user response:

In fact you have found out, just you output is the object's memory address
Want to be the format you want to rewrite the Login toString method

CodePudding user response:

Thank you for your reply, I already rewrite the toString method, or not, still the same result

Stick your toString code out

This is my add toString code:
Public class Login {

private String name;
private String password;
Public String getName () {
return name;
}
Public void elegantly-named setName (String name) {
this.name=name;
}
Public String getPassword () {
Return the password;
}
Public void setPassword (String password) {
this.password=password;
}
@ Override
Public String toString () {
Return "Login [name=" + name + ", "=" + "+"] ".
}

}

}
Public void setPassword (String password) {
this.password=password;
}
@ Override
Public String toString () {
Return "Login [name=" + name + ", "=" + "+"] ".
}

}

So should have no problem, see if you have caching, such as check again
