ibatis中xml里sql如何使用常量呢
比如select * from stu where id = ‘5’
我想直接写个5
[解决办法]
还是每次传进去吧。
或者这样试试：
Account.java
public class Account {
private int id;
private String firstName;
private String lastName;
private String emailAddress;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getEmailAddress() {
return emailAddress;
}
public void setEmailAddress(String emailAddress) {
this.emailAddress = emailAddress;
}
}
<?xml version="1.0" encoding="UTF-8" ?>
