前端页面代码(user.html)

启动运行并查看日志

打开浏览器查看

前提是Oracle已经启动并可访问，可以用tnsping测试oracle的可访问性。

pom.xml关键部分

注意这里是spring-boot-starter-jdbc，不要笔误写成spring-boot-starter-data-jdbc而导致类似报错如【Error creating bean with name 'jdbcConverter' defined in class path resource】

application.properties中的Oracle连接参数

特别注意oracle.jdbc.driver.OracleDriver与oracle.jdbc.OracleDriver有差别，下面这条配置会报错：Registered driver with driverClassName=oracle.jdbc.driver.OracleDriver was not found, trying direct instantiation.

spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver

正确配置为：

spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

application.properties完整内容

Model代码


package com.wdh.tacocloud.model;
 
import lombok.Data;
import lombok.RequiredArgsConstructor;
 
/**
 * @author WangDH
 * @create 2022-09-05 14:49
 */
@Data
@RequiredArgsConstructor
public class User {
 
    //private Long id;
 
    private String UserId;
 
    private String UserName;
 
    public User(String ui_id, String ui_name) {
        this.UserId=ui_id;
        this.UserName=ui_name;
    }
}

UserRepository及其实现类的代码


package com.wdh.tacocloud.data;
 
import com.wdh.tacocloud.model.User;
import java.util.List;
 
/**
 * @author WangDH
 * @create 2022-09-05 14:00
 */
public interface UserRepository {
    int getCount();
 
    List findAll();
 
    User findById(String userId);
}


package com.wdh.tacocloud.data.impl;
 
import com.wdh.tacocloud.data.UserRepository;
import com.wdh.tacocloud.model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;
 
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.List;
 
/**
 * @author WangDH
 * @create 2022-09-05 14:01
 */
@Repository
public class JdbcUserRepository implements UserRepository {
 
    JdbcTemplate jdbcTemplate;
 
    @Autowired
    public JdbcUserRepository(JdbcTemplate jdbc){
        this.jdbcTemplate=jdbc;
    }
 
    @Override
    public int getCount() {
        int count= jdbcTemplate.queryForObject("select count(*) from USER_INFO",Integer.class);
        return count;
    }
 
    @Override
    public List findAll() {
 
        List list=jdbcTemplate.query("select UI_ID,UI_NAME from USER_INFO",this::mapRowToUser);
 
        return list;
    }
 
    @Override
    public User findById(String userId) {
        return null;
    }
 
    private User mapRowToUser(ResultSet rs,int rowNum) throws SQLException {
        User user=new User(
                rs.getString("UI_ID"),
                rs.getString("UI_Name")
        );
        return user;
    }
}

访问数据库中返回有中文字符时报错的处理

IDEA console报错内容

2022-09-05 15:15:11.119 ERROR 6116 --- [nio-8080-exec-2] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.jdbc.UncategorizedSQLException: StatementCallback; uncategorized SQLException for SQL [select UI_ID,UI_NAME from USER_INFO]; SQL state [99999]; error code [17056]; 不支持的字符集 (在类路径中添加 orai18n.jar): ZHS16GBK; nested exception is java.sql.SQLException: 不支持的字符集 (在类路径中添加 orai18n.jar): ZHS16GBK] with root cause

java.sql.SQLException: 不支持的字符集 (在类路径中添加 orai18n.jar): ZHS16GBK

解决办法：pom中增加orai18n的依赖

com.oracle.ojdbc
orai18n
19.3.0.0

Controller代码


package com.wdh.tacocloud.controller;
 
import com.wdh.tacocloud.data.UserRepository;
import com.wdh.tacocloud.model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
 
import java.util.List;
 
/**
 * @author WangDH
 * @create 2022-09-05 15:59
 */
@Controller
@RequestMapping("/user")
public class UserController {
 
    private UserRepository userRepo;
 
    @Autowired
    public UserController(
            UserRepository userRepository
    ) {
        this.userRepo=userRepository;
    }
 
 
    @GetMapping
    public String showDesignForm(Model model){
 
        List listUser=userRepo.findAll();
        System.out.println("user list count="+listUser.size());
 
        //添加list标签属性到Model中便于前端html页面Thymeleaf根据list标签解析获取数据
        model.addAttribute("list",listUser);
 
        return "user";//映射到user.html
    }
 
}

前端页面代码(user.html)


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>User Taco cloud</title>
    <link rel="stylesheet" th:href="@{/styles.css}" />
</head>
<body>
<h2>Design your user,4</h2>
 
<form method="post">
 
    <table border="1">
        <tr>
            <th>用户ID</th>
            <!--<th>姓名</th>-->
        </tr>
        <tr  th:each="info : ${list}" >
            <td th:text="${info.UserId}"></td>
            <!--<td th:text="${info.UserName}"></td>-->
        </tr>
    </table>
 
</form>
 
</body>
</html>

TacocloudApplication.java


package com.wdh.tacocloud;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
public class TacocloudApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(TacocloudApplication.class, args);
    }
 
}

启动运行并查看日志
