今天尝试不抄网上的代码,借鉴一下自己尝试写。
创建jdbctemplate:
package com.weixiao;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
public class JdbcTemplateTest implements BiageDao {
@Autowired
//注入jdbc
private JdbcTemplate jdbcTemplate;
@Override
@Test
public int sayHello(Biage bg) {
String sql="INSERT INTO book(name,type,id) VALUES(?,?,?)";
Object[] args={bg.getName(),bg.getType(),bg.getId()};
int update = jdbcTemplate.update(sql, args);
return update;
}
}
package com.weixiao;
public class BiageServic {
private Biage biage;
public void setBiage(Biage biage) {
this.biage = biage;
}
public int addBook(Biage biage){
System.out.println("添加业务逻辑处理。。。");
return Biage.sayshllo(biage);
}
}
package com.weixiao;
import java.io.Serializable;
class Biage implements Serializable {
private Integer Id;
private String Name;
private String Type;
private String School;
public Integer getId() {
return Id;
}
public void setId(Integer id) {
Id = id;
}
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public String getType() {
return Type;
}
public void setType(String type) {
Type = type;
}
public String getSchool() {
return School;
}
public void setSchool(String school) {
School = school;
}
private String School;
public Biage(){
}
@Override
public String toString() {
return "biage{" +
"id=" + Id +
", name='" + Name + '\'' +
", type=" + Type +
", school='" + School + '\'' +
'}';
}
}

遇到问题:
代码编写时候,单段代码真的意思,可要连起来就不太理解了。
