Spring Boot 入门之数据库篇



由于授权问题,Maven3不提供Oracle JDBC driver，为了在Maven项目中应用Oracle JDBC driver,必须手动添加到本地仓库。

步骤如下：

（1）下载Oracle驱动程序ojdbc7.jar

（2）获取Oracle版本，SELECT * FROM v$version

（3）加载到本地maven库中

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc7 -Dversion=11.2.0.1.0 -Dpackaging=jar -Dfile=ojdbc7.jar 

(4)安装成功后，在pom.xml文件中添加引用

  com.oracle  ojdbc7  11.2.0.1.0 

(5)编写VO类

public class Phones {   
   private String phoneid; 
 private String phone;  private String name;  private String phonelevel;  public String getPhoneid() {
      return phoneid;  }
   public void setPhoneid(String phoneid) {
      this.phoneid = phoneid;  }
   public String getPhone() {
      return phone;  }
   public void setPhone(String phone) {
      this.phone = phone;  }
   public String getName() {
      return name;  }
   public void setName(String name) {
      this.name = name;  }
   public String getPhonelevel() {
      return phonelevel;  }
   public void setPhonelevel(String phonelevel) {
      this.phonelevel = phonelevel;  }
}

（6）编写service

public class UserService {
    @Autowired  private JdbcTemplate jdbcTemplate; 
 /**  * 获取联系人信息  * @return  */  public List getPhoneList() {
        List phonelist = new ArrayList();  String sql = "select phoneid,phone,name,phonelevel from PHONELIST";  phonelist = jdbcTemplate.query(sql, new RowMapper() {
            public Phones mapRow(ResultSet rs, int index) throws SQLException {
                Phones msg = new Phones();  msg.setPhoneid(rs.getString("phoneid"));  msg.setPhone(rs.getString("phone"));  msg.setName(rs.getString("name"));  msg.setPhonelevel(rs.getString("phonelevel"));  return msg;  }
        });  return phonelist;  }

(7)编写Controller

@RestController public class HelloController {
    @Autowired  private UserService userService;
    @RequestMapping("/users")
    public List getUserList(){

        return userService.getPhoneList();  }
}

（8）访问地址http://127.0.0.1:8080/users ，即可看到结果。
