Java-Web servlet控制器的引入

一、建包

二、建立实体类

　　参考二维表，考虑各个字段的名字、类型

private String id;
private String name;
private String address;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
