首先去你的 pom.xml里面看看依赖配置对不对,然后看下你的yml,,我的给你参考下

这是pom.xml依赖:

<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>

这是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

这是代码建的表

@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;
}

下面是代码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);
}
