Hibernate PropertyAccessException. Spring dependencies problem-CodePudding

My application originally used only Hibernate and everything worked fine, but with Spring i'm getting an exception. It feels like Spring causes different behavior for Hibernate.

So with Spring & Hibernate i get this exception trace:

All of my DAO methods for mysql are written with sessionFactory

Links - my only table

@Entity(name = "links")
@Table(name = "links")
@DynamicInsert // To set initial value of fields, otherwise doesn't work
public class Links implements Serializable {
@Id
private String link;
@Enumerated
@Column(columnDefinition = "smallint")
private Status status;
@Version
private int version;
private int depth;
private long owner;

public Links() {
} // hibernate requirement

public Links(String link, Status status, int depth) throws URISyntaxException {
    assert depth >= 0;
    assert !LinkParser.isBlank(link);

    this.link = link;
    this.status = status;
    this.depth = depth;
    this.owner = 0;
}

public String getLink() {
    return link;
}

private void setLink(String link) {
    this.link = link;
}

public int getVersion() {
    return version;
}

private void setVersion(int version) {
    this.version = version;
}

public Status getStatus() {
    return status;
}

public void setStatus(Status status) {
    this.status = status;
}

public int getDepth() {
    return depth;
}

private void setDepth(int depth) {
    this.depth = depth;
}

public long getOwner() {
    return owner;
}

public void setOwner(long owner) {
    assert owner >= 0;
    this.owner = owner;
}

application.properties

server.port=8080
server.servlet.context-path=/webcrawler

Only difference is when i start application with Spring, i dont get these exceptions when i dont use Spring.

CodePudding user response：

I think the issue is from the fact that you setter is private and should be public

private void setLink(String link) {
    this.link = link;
}

Should be

public void setLink(String link) {
    this.link = link;
}

Same for setVersion and setDepth

CodePudding user response：

I found out, I commented these maven dependencies

And everything started working... I guess devtools are the reason, dont want to check, i tried so many other stuff, and this is the reason...
