使用springboot暴露oracle数据接口的问题

新建一个Spring Initializr项目

2.把pom.xml文件中的oracle依赖换成自己的oracle版本依赖：

原来的：

现在的：

 
            com.oracle
            ojdbc6
            11.2.0.1.0

3.编辑application.yml

spring:
  datasource:
    driver-class-name: oracle.jdbc.driver.OracleDriver
    url: jdbc:oracle:thin:@192.168.21.200:1521:orcl
    username: alisa
    password: alisa

4.创建实例类——Userinfos.java：

package cn.alisa.myspboracle.entity;
 
import java.util.Date;
 
public class Userinfos {
    private int userid;
    private String username;
    private Date birthyear;
    private float userhight;
 
    public int getUserid() {
        return userid;
    }
 
    public void setUserid(int userid) {
        this.userid = userid;
    }
 
    public String getUsername() {
        return username;
    }
 
    public void setUsername(String username) {
        this.username = username;
    }
 
    public Date getBirthyear() {
        return birthyear;
    }
 
    public void setBirthyear(Date birthyear) {
        this.birthyear = birthyear;
    }
 
    public float getUserhight() {
        return userhight;
    }
 
    public void setUserhight(float userhight) {
        this.userhight = userhight;
    }
}

创建接口类——UserinfosDAO.java

package cn.alisa.myspboracle.dao;
 
import cn.alisa.myspboracle.entity.Userinfos;
import org.apache.ibatis.annotations.Select;
 
import java.util.List;
 
public interface UserinfosDAO {
    @Select("select userid,username,birthyear,userhight from userinfos")
    public ListfindAll();
 
    @Select("select userid,username,birthyear,userhight from userinfos where username like '%${name}%'")
    public ListfindUserSameName(String name);
}

创建服务类——UserinfosService.java

package cn.alisa.myspboracle.service;
 
import cn.alisa.myspboracle.dao.UserinfosDAO;
import cn.alisa.myspboracle.entity.Userinfos;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
import java.util.List;
 
@Service
public class UserinfosService {
    @Autowired
    private UserinfosDAO udao;
 
    public ListsearchAll(){
        return udao.findAll();
    }
 
    public ListsameName(String name){
        return udao.findUserSameName(name);
    }
}

创建控制层类——InitCtrl.java:

package cn.alisa.myspboracle.ctrl;
 
import cn.alisa.myspboracle.entity.Userinfos;
import cn.alisa.myspboracle.service.UserinfosService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
import java.util.List;
 
@RestController
public class InitCtrl {
    @Autowired
    private UserinfosService userinfosService;
 
    @RequestMapping("/all")
    public Listinit(){
        return userinfosService.searchAll();
    }
 
    @RequestMapping("/same")
    public Listsame(String name){
        return userinfosService.sameName(name);
    }
}

编辑MyspboracleApplication.java类：

package cn.alisa.myspboracle;
 
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
@MapperScan("cn.alisa.myspboracle.dao")
public class MyspboracleApplication {
 
    public static void main(String[] args) {
 
        SpringApplication.run(MyspboracleApplication.class, args);
    }
 
}
