Spring Boot入门——JDBCTemplate使用及其相关问题解决

1、在pom.xml文件中引入相应依赖

    <!-- mysql依赖 -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.42</version>
    </dependency>
    
    <!-- jdbc依赖 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jdbc</artifactId>
    </dependency>

2、创建Grade类

public class Grade {

    private int id;
    private String gradeNm;
    private int teacherId;
    
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getGradeNm() {
        return gradeNm;
    }
    public void setGradeNm(String gradeNm) {
        this.gradeNm = gradeNm;
    }
    public int getTeacherId() {
        return teacherId;
    }
    public void setTeacherId(int teacherId) {
        this.teacherId = teacherId;
    }
}
