ORM映射关系编码
创建Stock类对应数据库2的stock表
@Entity
@Table(name = "stock")
@NamedQuery(name = "Stock.findAll",
query = "SELECT f FROM Stock f",
hints = @QueryHint(name = "org.hibernate.cacheable", value = "true") )
@Cacheable
@PersistenceUnit(name = "stock")
public class Stock {
@Id
@Column(name = "id", length = 20, unique = true)
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "product_id", length = 11)
private Long productId;
@Column(name = "total_count", length = 11)
private Integer totalCount;
@Column(name = "create_time")
private Date createTime;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Long getProductId() {
return productId;
}
public void setProductId(Long productId) {
this.productId = productId;
}
public Integer getTotalCount() {
return totalCount;
}
public void setTotalCount(Integer totalCount) {
this.totalCount = totalCount;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
@Override
public String toString() {
return "Stock{" +
"id=" + id +
", productId=" + productId +
", totalCount=" + totalCount +
", createTime=" + createTime +
'}';
}
}
StockService操作数据库的Service
@ApplicationScoped
public class StockService {
@Inject
@Named("stock")
EntityManager manager;
@Transactional(rollbackOn = Exception.class)
public void createUserCount() {
Stock stock = new Stock();
stock.setCreateTime(new Date());
stock.setTotalCount(10000);
stock.setProductId(2L);
manager.persist(stock);
}
public List<Stock> findAll() {
return manager.createNamedQuery("Stock.findAll", Stock.class).getResultList();
}
}
创建UserAccount类对应数据库1的user_account表
@Entity
@Table(name = "user_account")
@NamedQuery(name = "UserAccount.findAll",
query = "SELECT f FROM UserAccount f",
hints = @QueryHint(name = "org.hibernate.cacheable", value = "true") )
@Cacheable
@PersistenceUnit(name = "bank01")
public class UserAccount {
@Id
@Column(name = "id", length = 11, unique = true)
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
@Column(name = "account_no", length = 64, unique = true)
private String accountNo;
@Column(name = "account_name", length = 50)
private String accountName;
@Column(name = "account_balance", length = 10)
private Double accountBalance;
@Column(name = "transform_balance", length = 10)
private Double transformBalance;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getAccountNo() {
return accountNo;
}
public void setAccountNo(String accountNo) {
this.accountNo = accountNo;
}
public String getAccountName() {
return accountName;
}
public void setAccountName(String accountName) {
this.accountName = accountName;
}
public Double getAccountBalance() {
return accountBalance;
}
public void setAccountBalance(Double accountBalance) {
this.accountBalance = accountBalance;
}
public Double getTransformBalance() {
return transformBalance;
}
public void setTransformBalance(Double transformBalance) {
this.transformBalance = transformBalance;
}
@Override
public String toString() {
return "UserCount{" +
"id=" + id +
", accountNo='" + accountNo + '\'' +
", accountName='" + accountName + '\'' +
", accountBalance='" + accountBalance + '\'' +
", transformBalance='" + transformBalance + '\'' +
'}';
}
}
UserAccountService操作数据库的Service
@Singleton
public class UserAccountService {
@Inject
@Named("bank01")
EntityManager manager;
@Transactional(rollbackOn = Exception.class)
public void createUserCount() {
UserAccount userCount = new UserAccount();
userCount.setAccountName("刘p辉");
userCount.setAccountNo("1003");
userCount.setTransformBalance(100.0);
userCount.setAccountBalance(1000.0);
manager.persist(userCount);
}
public List<UserAccount> getUserCount() {
return manager.createNamedQuery("UserAccount.findAll", UserAccount.class).getResultList();
}
}
HTTP接口Resource的编写
- StockResource
@Path("/stock")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class StockResource {
private static final Logger log = LoggerFactory.getLogger(UserAccountResource.class);
@Inject
StockService stockService;
@GET
@Path("/getAll")
@Logged
public Response getAll() {
HttpResponseDTO<Object> responseDTO = HttpResponseDTO
.builder()
.resCode("0000")
.resMessage("成功")
.resData(stockService.findAll())
.build();
return Response.ok(responseDTO).build();
}
@POST
@Path("/create")
@Logged
public Response createUserCount() {
stockService.createUserCount();
HttpResponseDTO<Object> responseDTO = HttpResponseDTO
.builder()
.resCode("0000")
.resMessage("成功")
.resData(stockService.findAll())
.build();
return Response.ok(responseDTO).build();
}
}
- UserAccountResource
@Path("/account")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class UserAccountResource {
private static final Logger log = LoggerFactory.getLogger(UserAccountResource.class);
@Inject
UserAccountService userCountService;
@GET
@Path("/getAll")
@Logged
public Response order() {
HttpResponseDTO<Object> responseDTO = HttpResponseDTO
.builder()
.resCode("0000")
.resMessage("成功")
.resData(userCountService.getUserCount())
.build();
return Response.ok(responseDTO).build();
}
@POST
@Path("/create")
@Logged
public Response createUserCount() {
userCountService.createUserCount();
HttpResponseDTO<Object> responseDTO = HttpResponseDTO
.builder()
.resCode("0000")
.resMessage("成功")
.resData(userCountService.getUserCount())
.build();
return Response.ok(responseDTO).build();
}
}
