osx sierra intellij spring boot jdk 8 slow startup

My spring boot applications startup time was very long with jdk 8. There is no problem with jdk 9. A simple application without any code startup time was over 15 seconds. Now it starts under 5 seconds. I find solution in stackoverflow :

solved the problem by adding my Mac hostname (i.e. Macbook.local, or whatever your Mac is called) on the /etc/hosts file mapped to the address as well as the ::1 like this:   localhost mbpro.local
::1         localhost mbpro.local

To learn your hostname, type hostname in the console.



Integrating Angular and Spring Boot in one project and running on one server


  1. After creating spring boot project to create Angular project on the same folder :
    From root directory firstly go upper directory

    cd ..

    create new ng project with same spring boot directory name (example: bootang) , and i set src/main/app for Angular source

    ng new bootang -sd src/main/app
  2. Change output directory for Angular output in .angular-cli.json :
    "outDir": "src/main/webapp",
  3. Build angular app :
    ng build

    If you run with -w (watch) parameter, it will refresh angular build files.
    Like ng serve

    ng build -w
  4. Run your spring boot application and you will see Spring Boot and Angular runs on same server (default localhost:8080)I think this way is better/simple than JHipster ‘s lots of webpack configuration 🙂

Hibernate Auditing – Base Entity and Example Entity

Add Hibernate envers dependency to your pom.xml file :


This is base entity class for enabling auditing :

public class BaseEntity implements Serializable{

    private static final long serialVersionUID = -1591130256151148932L;

    @Column(nullable = false,length = 50,updatable = false)
    private String createdBy;

    @Column(nullable = false)
    private Instant createdDate = Instant.now();

    @Column(length = 50)
    private String updatedBy;

    private Instant updatedDate = Instant.now();

Example User entity extends BaseEntity :

public class User extends BaseEntity implements Serializable {

    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(length = 100,unique = true,nullable = false)
    private String login;

    private String password;
    private String firstName;
    private String lastName;
    private boolean active = false;
    private String email;

    @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)
    private Set<Role> roles = new HashSet<>();

If a relationship entity in your entity is not audited, then you should add annotation  :
@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)

For adding for example “ZLOG_” prefix to your audit tables in your spring boot application.yml file :

      org.hibernate.envers.audit_table_prefix: ZLOG_

Issue with the rowEdit event in p:dataTable Primefaces component

The issue was in the following: when I try to edit row in the dataTable, all is going well. But when I try to save the changes, the new value doesn’t retrieve and new value has not been saved.

In the getAll method of the generic dao do null control :

if (listItems == null){
            listItems = (List<Item>) genericDao.getAll();
        return listItems;

glassfish hibernate binding parameters, easy way

when you search for showing parameters in hibernate. All articles will say that put these lines in log4j.properties :


but if you are using glassfish this will not work. and you will find this glassfish way :


but there is a more easy way :

Glassfish admin console -> Configurations -> Server-config -> Logger Settings -> Log levels -> Add Logger -> org.hibernate.type : FINEST

glassfish logger settings

I am using intellij idea with glassfish and in the console i see this long message for every line :

[2013-01-29T15:27:39.395-0500] [glassfish 4.0] [INFO] [AS-JMX-00005] [javax.enterprise.system.jmx] [tid: _ThreadID=49 _ThreadName=Thread-6] [timeMillis: 1359491259395] [levelValue: 800] [[ …

to reduce and shorten the messages, go to  glassfish admin console -> configurations -> server-config -> logger-settings :

select all fields in the format exclude fields and click save.

and shorten your log4j pattern in log4j.properties. From :

log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

to this pattern :

log4j.appender.stdout.layout.ConversionPattern=%c{1}:%L - %m%n
