java - "Error starting ApplicationContext"执行spring应用时

Question

我有几个微服务，其中两个运行良好，但在另外两个上我遇到了一些错误。数据库模式尚未创建，但通常是在我成功启动应用程序后创建的。我得到了类似的运行类，我已经尝试了一些事情，比如删除我在 .m2 文件夹中的存储库，但没有成功。我也在使用 eureka 发现服务和 eureka zuul。

我不确定，但我认为它无法找到数据库模式。当我在另一个类似的项目中添加一个 @Entity 注释时，它第一次失败了。

更新

我发现我在 java 类中两次使用了相同的列名称。所以第一个应用程序再次运行。但是当我使用诸如 @Entity 或 @Column 之类的注释时，第二个(类似的体系结构)不会运行。当我删除它们时，一切正常。错误信息是一样的。

更新 2我认为这是以下两个类之间的逻辑问题。我现在已经筋疲力尽了。

package de.leuphana.jee.component.structure;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

@Entity
public class AddressEntity {

private Integer addressId;
private String city;
private String street;
private int zip;

public AddressEntity(String city, String street, int zip) 
{
    this.city = city;
    this.street = street;
    this.zip = zip;
}

public AddressEntity() {

}

@Id
@GeneratedValue
public Integer getAddressId() {
    return addressId;
}

@Column(name = "city")
public String getCity() {
    return city;
}

public void setCity(String city) {
    this.city = city;
}

@Column(name = "street")
public String getStreet() {
    return street;
}

public void setStreet(String street) {
    this.street = street;
}

@Column(name = "zip")
public int getZip() {
    return zip;
}

public void setZip(int zip) {
    this.zip = zip;
}

}

package de.leuphana.jee.component.structure;

import java.time.LocalDate;
import java.util.HashSet;
import java.util.Set;

import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;

@Entity
public class OrderEntity {

private Set<AddressEntity> addresses;

private Integer orderId;
private Set<OrderItemEntity> orderItemsEntitySet;

public OrderEntity(AddressEntity addressEntity, LocalDate orderDate) {
    addresses = new HashSet<>();
    addresses.add(addressEntity);
    this.orderDate = orderDate;
    orderItemsEntitySet = new HashSet<>();
}

}

@Id

老问题(pom.xml/application.properties 在每个项目中都是相似的)

Java 类:

package de.leuphana.jee.component.structure;

import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToOne;

@Entity
public class CustomerEntity {
// intrinsic attribute
private Integer customerId;

// relational attribute
private CartEntity cartEntity;

@Id
@GeneratedValue
public Integer getCustomerId() {
    return customerId;
}

public void setCustomerId(Integer customerId) {
    this.customerId = customerId;
}

@OneToOne(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
public CartEntity getCartEntity() {
    return cartEntity;
}

public void setCartEntity(CartEntity cartEntity) {
    this.cartEntity = cartEntity;
}

}

Answer 1

解决了问题

这个问题不符合逻辑，至少不是我预期的那样。我没有 addressId 的 setter 方法!现在觉得自己好傻。我的代码无法为 AddressEntity

设置主键
