Spring/Hibernate Write operations are not allowed in read-only mode

Spring/Hibernate Write operations are not allowed in read-only mode - java

I've read some of other questions on the same topic, but in my case I'm not actually specifying anything. What makes me really confused is I have another call that works. I don't specify any transactions so I'm not sure why this is becoming a problem.
This is what happens when I try to use xssSave() (in the service class at the bottom), but sqlInject (also in the same class) works fine. As far as I can tell these operate identically except that one works and one doesn't.
If you want to view the full code and/or check it out yourself, it's available on GitHub (https://github.com/tenmilez/WebBilly).

HibernateTemplate doesn't manage transactions, you need a HibernateTransactionManager instead.
The write operations need to execute within the context of a transaction, so you need to also annotate you DAO or your services with #Transactional.

I'm newer in java development. I want to add validators to our project. But I had a problem. Please help me!
I add

And my DTO:

I have no idea what's wrong. I google,but I can't find something else like this, pls help me. thank you!
According to m4gic's suggestion.I try code a demo:
controller
#RequestMapping(value="/index")
#ResponseBody
public DataResult<User> index(#Valid User request,Errors errors){
User user = new User();
DataResult<User> result = new DataResult<>();
if(errors.hasErrors()){
result.setMsg(errors.getAllErrors().get(0).getDefaultMessage());
}
result.setData(user);
return result;
}
User.java
public class User implements Serializable {
private static final long serialVersionUID = 1L;
#NotBlank(message = "name is null!")
private String name;
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
DataResult.java
public class DataResult<T> implements Serializable {
private static final long serialVersionUID = 1L;
private int code;
private String msg;
private T data;
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public T getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
}
But It works well.NO error;Result:
{
"code": 0,
"msg": "name is null!",
"data": {
"name": null,
"age": 0
}
}

I think what you definitely can do is to try to handle validation errors in different way.
Maybe the problem is that you are trying to handle errors in a controller function having #ResponseBody that would mean that the error should be given back as json. If you would use controlleradvice or custom exception handler, that may help you out.
The other thing you can do is to create a proper spring boot project (after figuring out that using boot 1.4.0.RELEASE will create a project that will contain spring 4.3.2.RELEASE and everything else that is compatible). Then try to reproduce your error in this project (with boot-controlled compatible dependency-set). If there is no error, then you have to compare the two projects dependency tree, because very probably you are using some incompatible jars.

Since you are using Hibernate, check if you have bidirectional mapping. Those can cause infinite recursion. For example if you have parent class A and child class B, and A has list of B`s but B also have reference to its parent A. This will be major problem for serialization. Solution is to either break bidirectional mapping or implement some kind of guard to not populate field of type A in class B.

How to create emdedded H2 DB with spring(transactional) and hibernate in java desktop application?

I am trying to create a project with embedded h2 db, and using spring framework with hibernate. My database will be created in initialize time if not exist. My development platform is intellij.
Problem is that when i run the application

here is my classes and config files.
myDB.sql:

An IPersonDao interface and here is implemented class

There is an IPersonService interface and here is implemented class

public class PersonelServiceImpl implements IPersonelService {
#Autowired
private IPersonelDao personelDao;
#Override
#Transactional
public void savePersonel(Personel personel) {

#Override
#Transactional
public List<Personel> getPersonels() {
return personelDao.getPersonels();
}
}
here is my main class
public class MainApp {
private static ApplicationContext applicationContext;
public static void main(String[] args) {
applicationContext = new ClassPathXmlApplicationContext("hibernate-config.xml");
ForExample a = new ForExample();
a.execute();
}
}
#Component
public class ForExample {
#Autowired
private IPersonelService personelService;
public void execute(){
Personel p = new Personel();
p.setName("thats Ok!");
p.setAge("614345");
personelService.savePersonel(p);
}
}

public class MainApp {
public static ApplicationContext applicationContext;
private static IPersonelService personelService;
public static void main(String[] args) {
applicationContext = new ClassPathXmlApplicationContext("hibernate-config.xml");
personelService = applicationContext.getBean(IPersonelService.class);
Personel p = new Personel();
p.setName("thatsOK!");
p.setAge("614345");
personelService.savePersonel(p);
}
}
Because of spring does not recognise new operator in run time..

I just add the following code in my controller...
Second thing is that you have to first redirect your index.jsp file to some other file...
#RequestMapping(method = RequestMethod.GET)
public String addEmployee(#ModelAttribute("a") A a, Model model,HttpServletRequest request)
{
return "addEmployee";
}

You don't match the correct URL in your JSP file.
Change this line on your JSP file :
<form:form commandName="course" action="addCourse" method="POST">
For:
<form:form commandName="course" action="/addCourse" method="POST">
Else, you can change your mapping on your controller:
#RequestMapping(value="/addCourse",method= RequestMethod.POST)
For:
#RequestMapping(value="addCourse",method= RequestMethod.POST)

as said in this post, error might occur while loading the jsp itself, and
more over binding might fail for below reasons
The binding results can be examined via the BindingResult interface,
extending the Errors interface: see the getBindingResult() method.
Missing fields and property access exceptions will be converted to
FieldErrors, collected in the Errors instance, using the following
error codes:
> Missing field error: "required"
> Type mismatch error: "typeMismatch"
> Method invocation error: "methodInvocation"
so check any type mismatches or field you might have missed, as i had faced this issue personally

How to fix "Duplicate property mapping" exception?

Edit: I tried commenting out the <mapping resource="entities/messages.hbm.xml"/> from the cfg file and I still get the same error.
Edit2: The above is from a java EE project, I copied paste everything in a simle java project and it worked fine. Any suggestion?
Edit3: I added the final modifier to messages class to be sure that it cannot be inherited

How to use HibernateTemplate directly in my testing code

I'm trying to make a quick small test on HibernateTemplate. But I always get exception: org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here.
How can I make the code work? Here're the codes:

I think you are trying to use unwrapped object instead of proxy enriched with transactional behavior. Your initialization should be:
private static SpringDao springRunner = (SpringDao) ctx.getBean("springDaoTarget");
Alter your names accordingly too. By the way TransactionProxyFactoryBean is considered "old style" nowadays. You may consider using #Transactional instead.

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Spring/Hibernate Write operations are not allowed in read-only mode - java

HibernateTemplate doesn't manage transactions, you need a HibernateTransactionManager instead. The write operations need to execute within the context of a transaction, so you need to also annotate you DAO or your services with #Transactional.
