Question

我有一台使用JPA，Hibernate和H2作为数据库的Spring服务器。

我的Function Start-Worker { $SyncHash = [hashtable]::Synchronized(@{TextBox = $TextBox}) $Runspace = [runspacefactory]::CreateRunspace() $Runspace.ThreadOptions = "UseNewThread" # Also Consider: ReuseThread $Runspace.Open() $Runspace.SessionStateProxy.SetVariable("SyncHash", $SyncHash) $Worker = [PowerShell]::Create().AddScript({ $ThreadID = [appdomain]::GetCurrentThreadId() $SyncHash.TextBox.Text = "Thread $ThreadID has started" for($Progress = 0; $Progress -le 100; $Progress += 10) { $SyncHash.TextBox.Text = "Thread $ThreadID at $Progress%" Start-Sleep 1 # Some background work } $SyncHash.TextBox.Text = "Thread $ThreadID has finnished" }) $Worker.Runspace = $Runspace $Worker.BeginInvoke() } [Void][System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") $Form = New-Object Windows.Forms.Form $TextBox = New-Object Windows.Forms.TextBox $TextBox.Visible = $False $TextBox.Add_TextChanged({Write-Host $TextBox.Text}) $Form.Controls.Add($TextBox) $Button = New-Object System.Windows.Forms.Button $Button.Text = "Start worker" $Button.Add_Click({Start-Worker}) $Form.Controls.Add($Button) $Form.ShowDialog()是：

application.properties

一切正常，直到我在表格中添加新列。

我是用H2控制台做的：

我使用以下语法添加了新列：

spring.datasource.url=jdbc:h2:/xxx/database;AUTO_SERVER=TRUE
spring.datasource.driverClassName=org.h2.Driver
spring.jpa.show-sql: true
spring.jpa.hibernate.ddl-auto=update
log4j.logger.org.hibernate=error
spring.datasource.username=xxx
spring.datasource.password=yyy

之后，我第一次运行Spring Server，一切运行完美。 当我停止服务器并再次启动时出现问题。出现此错误消息：

ALTER TABLE POINT ADD COLUMN USEDMAP BOOLEAN DEFAULT FALSE

此错误显示同一个表12:27:02.248 ERROR 11895 --- [ost-startStop-1] org.hibernate.tool.hbm2ddl.SchemaUpdate : HHH000299: Could not complete schema update org.h2.jdbc.JdbcSQLException: Unique index or primary key

我的Point java类是：

Point

为什么要尝试更新从未修改的@Entity public class Point { @Id @GeneratedValue(strategy=GenerationType.AUTO) long id; @ElementCollection(fetch=FetchType.EAGER) @Column(columnDefinition="VARCHAR(10000)") Map<Long, String> paramanswer = new HashMap<Long, String>(); long projectid; double latitude; double longitude; boolean verified_gps; boolean current; boolean readytosend; String name; String address; //INCLUDING ADDRESS, NUMBER AND NEIGHBOURHOOD String city; String state; String country; @Size(max=10000) String description; long date; boolean android_received; boolean edited; long pointtype; String researcher; boolean usedmap; public Map<Long, String> getParamanswer() { return paramanswer; } public void setParamanswer(Map<Long, String> paramanswer) { this.paramanswer = paramanswer; } public Point() {} public boolean isUsedmap() { return usedmap; } public void setUsedmap(boolean usedmap) { this.usedmap = usedmap; } public long getPointtype() { return pointtype; } public void setPointtype(long pointtype) { this.pointtype = pointtype; } public boolean isEdited() { return edited; } public void setEdited(boolean edited) { this.edited = edited; } public boolean isReadytosend() { return readytosend; } public void setReadytosend(boolean readytosend) { this.readytosend = readytosend; } public long getDate() { return date; } public void setDate(long date) { this.date = date; } public boolean isCurrent() { return current; } public void setCurrent(boolean current) { this.current = current; } public List<Long> getIdsurveys_list() { return idsurveys_list; } public void setIdsurveys_list(List<Long> idsurveys_list) { this.idsurveys_list = idsurveys_list; } public boolean isVerified_gps() { return verified_gps; } public void setVerified_gps(boolean verified_gps) { this.verified_gps = verified_gps; } public String getResearcher() { return researcher; } public void setResearcher(String researcher) { this.researcher = researcher; } public long getId() { return id; } public void setId(long id) { this.id = id; } public long getProjectid() { return projectid; } public void setProjectid(long projectid) { this.projectid = projectid; } public double getLatitude() { return latitude; } public void setLatitude(double latitude) { this.latitude = latitude; } public double getLongitude() { return longitude; } public void setLongitude(double longitude) { this.longitude = longitude; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public String getCity() { return city; } public void setCity(String city) { this.city = city; } public String getState() { return state; } public void setState(String state) { this.state = state; } public String getCountry() { return country; } public void setCountry(String country) { this.country = country; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public boolean isAndroid_received() { return android_received; } public void setAndroid_received(boolean android_received) { this.android_received = android_received; } }变量？

Answer 1

为什么在使用hibernate.ddl-auto = update时手动添加新列？只需将新的布尔属性添加到实体类中，就应该自动添加它。或者不使用自动更新DDL策略。
