請問老師，我的創建了GirlProperties之后，java項目就啟動不起來了

首先去你的 pom.xml里面看看依賴配置對不對,然后看下你的yml,,我的給你參考下
這是pom.xml依賴:
<dependency>
? <groupId>org.springframework.boot</groupId>
? <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
? <groupId>org.springframework.boot</groupId>
? <artifactId>spring-boot-starter-test</artifactId>
? <scope>test</scope>
</dependency>
<dependency>
? <groupId>org.springframework.boot</groupId>
? <artifactId>spring-boot-configuration-processor</artifactId>
? <optional>true</optional>
</dependency>
<dependency>
? <groupId>org.springframework.boot</groupId>
? <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
? ? ?<dependency>
? ? ? ? ?<groupId>org.springframework.boot</groupId>
? ? ? ? ?<artifactId>spring-boot-starter-data-jpa</artifactId>
? ? ?</dependency>
? ? ?<dependency>
? ? ? ? ?<groupId>mysql</groupId>
? ? ? ? ?<artifactId>mysql-connector-java</artifactId>
? ? ?</dependency>
這是yml:
spring:
?profiles:
? ?active: test
?datasource:
? ?driver-class-name: com.mysql.jdbc.Driver
? ?url: jdbc:mysql://localhost:3306/test1
? ?username: root
? ?password: root
?jpa:
? ?hibernate:
? ? ?ddl-auto: update
? ?show-sql: true
這是代碼建的表
@Entity
public class Test {
? ?@Id
? ?@GeneratedValue
? ?private Integer ?id ;
? ?private String name;
? ?public Test(){
? ?}
? ?public Integer getId() {
? ? ? ?return id;
? ?}
? ?public void setId(Integer id) {
? ? ? ?this.id = id;
? ?}
? ?public String getName() {
? ? ? ?return name;
? ?}
? ?public void setName(String name) {
? ? ? ?this.name = name;
? ?}
下面是代碼controller:
@RestController
@RequestMapping("/test")
public class TestController {
? ?@Autowired
? ?private TestList list;
? ?@RequestMapping("/testList")
? ?public List<Test> TestList(){
? ? ? ?return list.findAll();
? ?}
? ?@RequestMapping("/ListById")
? ?public Test testById(String id ){
? ? ? ?return list.findOne(Integer.parseInt(id));
? ?}
? ?@RequestMapping("/delete")
? ?public String ?deleteTest(Integer ?id ){
? ? ? ?list.delete(id);
? ? ? ?return null;
? ?}
? ?@RequestMapping("/addTest")
? ?public Test insertTest(Integer id ,String name){
? ? ? ?Test test=new Test();
? ? ? ?test.setId(id);
? ? ? ?test.setName(name);
? ? ?return list.save(test);
? ?}
? ?@RequestMapping("/update")
? ?public Test updateTest(Integer id ,String name){
? ? ? ?Test test=new Test();
? ? ? ?test.setId(id);
? ? ? ?test.setName(name);
? ? ? ?return list.save(test);
? ?}
對了千萬別忘了接口:
public interface TestList extends JpaRepository<Test,Integer>{
?
}
