我想在 Spring Boot 中通过 STS 使用 JPA 和 SQL Server 这是我的桌子：

application.properties

spring.datasource.driver-class-  name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.url=jdbc:sqlserver://localhost:1433;databaseName=quanlybanhang
spring.datasource.username=sa
spring.datasource.password=1
spring.jpa.hibernate.ddl-auto=create
spring.datasource.initialize=true
spring.jpa.database=SQL_SERVER

Model.Account.class

  @Entity
  @Table(name="taikhoan",uniqueConstraints=@UniqueConstraint(columnNames =     "tendangnhap" ) )
 public class Account 
 @Id @GeneratedValue(strategy=GenerationType.AUTO)
 private int id;
 @NotNull

private String tendangnhap;
@NotNull
private String matkhau;
public Account(String tendangnhap, String matkhau) 
    super();
    this.tendangnhap = tendangnhap;
 this.matkhau = matkhau;

public Account() 
    super();

public int getId() 
    return id;

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

public String getTendangnhap() 
    return tendangnhap;


public void setTendangnhap(String tendangnhap) 
    this.tendangnhap = tendangnhap;

public String getMatkhau() 
    return matkhau;

public void setMatkhau(String matkhau) 
    this.matkhau = matkhau;
   

接口AccountDAO

public interface AccountDAO extends JpaRepository<Account, Integer>

ServiceAccount.class

@Service
public class ServerAccount 
    @Autowired
    AccountDAO server;
    public void them(Account acc)
        server.save(acc);   
    
    public List<Account> lietke()

        return server.findAll();    
    

ServicesAccount.class

@Service
public class ServerAccount 
    @Autowired
    AccountDAO server;

    Account acc=new Account("khang", "1");

    public void addAccount()
        server.save(acc);
    


    public List<Account> lietke()

        return server.findAll();    
    

我在 Controller 中调用了 addAccount() 方法，这是我得到的异常

“java.lang.NoClassDefFoundError: org/springframework/orm/jpa/support/PersistenceAnnotationBeanPostProcessor”

“引起：java.lang.ClassNotFoundException: org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor”

请帮我解决这个异常。谢谢！！！

【问题讨论】：

你的 pom 有没有 org.springframework.bootspring-boot-starter-parentxxxxx

是的，我的 pom.xml 有它。在我使用 mysql 之前，它没有任何异常或问题，但是当使用 SQLServer 时，我遇到了异常

【参考方案1】：

从您错过的依赖项中（检查您使用的 java 版本）：

 <dependency>
        <groupId>com.microsoft.sqlserver</groupId>
        <artifactId>mssql-jdbc</artifactId>
        <version>6.5.2.jre8-preview</version>
        <scope>test</scope>
    </dependency>

并在应用程序属性中更正这一行：

spring.datasource.driver-class-  name=com.microsoft.sqlserver.jdbc.SQLServerDriver

到

spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect

【讨论】：

属性 spring.jpa.hibernate.dialect 已更新为 spring.jpa.properties.hibernate.dialect
