目前，我在为我的springboot项目获取mysql数据时遇到了一个问题：
出现错误（类型=内部服务器错误，状态=500）。无法提取结果集; SQL [不适用];嵌套异常为组织休眠异常。SQLGrammarException：无法提取结果集

测试实体.java

@Entity
public class TestEntity implements Serializable {

    @Id
    private int id;
    private String p1;
    private String p2;
    private String p3;

    public TestEntity() {
    }

    public TestEntity(int id, String p1, String p2, String p3){
        this.id = id;
        this.p1 = p1;
        this.p2 = p2;
        this.p3 = p3;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getP1() {
        return p1;
    }

    public void setP1(String p1) {
        this.p1 = p1;
    }

    public String getP2() {
        return p2;
    }

    public void setP2(String p2) {
        this.p2 = p2;
    }

    public String getP3() {
        return p3;
    }

    public void setP3(String p3) {
        this.p3 = p3;
    }


}

测试服务.java

@Service
public class TestService {

    @Autowired
    private TestRepository testRepository;

    public ArrayList<TestEntity> getAllTestEntities(){
       ArrayList<TestEntity> list = new ArrayList();
       testRepository.findAll().forEach(list::add);
       return list;
    }

    public Optional getTestEntity(int id){
       return testRepository.findById(id);
    }
    public void addTestEntity(TestEntity t){
        testRepository.save(t);
    }
    public void removeTestEntity(int index){

        testRepository.deleteById(index);

    }

}

测试存储库.java

@Repository("mysql")
public interface TestRepository extends CrudRepository<TestEntity,Integer> {


}

测试控制器.java

@RestController
public class TestController {

    @Autowired
    private TestService testService;

    @RequestMapping("/test/AllUnits")
    public ArrayList<TestEntity> getAllTestUnits(){
        return testService.getAllTestEntities();
    }

    @RequestMapping("/test/{id}")
    public Optional getAllTestUnit(@PathVariable int id){
        return testService.getTestEntity(id);
    }

    @RequestMapping(method=RequestMethod.POST,value = "/test" )
    public void addTestUnit(@RequestBody TestEntity t){
        testService.addTestEntity(t);
    }

    @RequestMapping(method=RequestMethod.DELETE,value = "/test/{id}" )
    public void deleteTestUnit(@RequestBody Integer id){
        testService.removeTestEntity(id);
    }

    @RequestMapping("/test/welcome")
    public String welcome(){

        return "welcome to springboot";

    }

}

编辑：应用程序属性

cloud.aws.region.auto=true
cloud.aws.region.static=us-east-2

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://alyxdev.czcdgqfkwsnr.us-east-2.rds.amazonaws.com:3306/CryptoCurrency
spring.datasource.username=*******
spring.datasource.password=*******

我能够使/test/welcomeMap工作，因此我相信我的服务和控制器的实现是正确的。所以我想知道我是否在访问存储库中的数据库时犯了错误，或者我应该使用JpaRepository而不是CrudRepository并使用显式查询？

编辑堆栈跟踪：数据访问无效资源使用异常：无法提取结果集; SQL [不适用];嵌套异常为组织休眠异常。SQLGrammarException：无法提取结果集，原因是：org.hibernate.exception.SQLGrammarException:无法提取结果集，原因是：发生语法错误异常：表'加密货币.test_entity'不存在
