弹性搜索在Spring Boot应用程序中不起作用

Question

我正在使用Spring Boot，我想在我的解决方案中集成弹性搜索。我向实体添加了弹性搜索依赖项，配置，存储库和注释@Document，它可以正常工作。但是，当我对另一个实体执行相同的操作时，应用程序会生成错误：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

以及这是我的新实体定义

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.mongodb.core.mapping.DBRef;
import org.springframework.data.mongodb.core.mapping.Field;

import java.util.List;
import java.util.Objects;
@Document(indexName = "activity_group", type = "activity_group")
public class ActivityGroup implements Serializable {
private static final long serialVersionUID = 1L;

@Id
private String id;

@Field("code")
private String code;

@Field("name")
private String name;

@Field("description")
private String description;

@Field("color")
private String color;

@DBRef
@Field("requirements")
private List<Requirement> requirements;

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

public String getCode() {
    return code;
}

public ActivityGroup code(String code) {
    this.code = code;
    return this;
}

public void setCode(String code) {
    this.code = code;
}

public String getName() {
    return name;
}

public ActivityGroup name(String name) {
    this.name = name;
    return this;
}

public void setName(String name) {
    this.name = name;
}

public String getDescription() {
    return description;
}

public ActivityGroup description(String description) {
    this.description = description;
    return this;
}

public void setDescription(String description) {
    this.description = description;
}

public String getColor() {
    return color;
}

public ActivityGroup color(String color) {
    this.color = color;
    return this;
}

public void setColor(String color) {
    this.color = color;
}


public List<Requirement> getRequirements() {
    return requirements;
}

public void setRequirements(List<Requirement> requirements) {
    this.requirements = requirements;
}

@Override
public boolean equals(Object o) {
    if (this == o) {
        return true;
    }
    if (o == null || getClass() != o.getClass()) {
        return false;
    }
    ActivityGroup activityGroup = (ActivityGroup) o;
    if (activityGroup.getId() == null || getId() == null) {
        return false;
    }
    return Objects.equals(getId(), activityGroup.getId());
}

@Override
public int hashCode() {
    return Objects.hashCode(getId());
}

@Override
public String toString() {
    return "ActivityGroup{" +
            "id=" + getId() +
            ", code='" + getCode() + "'" +
            ", name='" + getName() + "'" +
            "}";
}

}

Answer 1

您正在同一类中同时使用elasticsearch和mongo映射注释。

import org.springframework.data.mongodb.core.mapping.DBRef; 
import org.springframework.data.mongodb.core.mapping.Field;

如果必须在同一项目中同时使用mongodb和elasticsearch，则需要为两个数据源定义不同的实体，并分别使用相应的注释。
