I m creating from page for customer so everything works well until i wanted to force the user to enter a number in the field "free passes" i got error
i've tried to creat a field with Integer type named freePasses in the Customer class then generate the getter and setters for it, i've alslo modify my .properties file
Customer.java
#Min(value = 0 , message="the value must be equal or greater than 0")

public Integer getFreePasses() {
return freePasses;
}

Failed to convert property value of type java.lang.String to required type java.lang.Integer for property freePasses; nested exception is java.lang.NumberFormatException: For input string: "44xxxx"
I think <form:input type=?number? path="date" /> will work.
create file: src/resources/messages.properties
and write this line:
typeMismatch.customer.freePasses= Invalid number
Solution 1 : Add below code in your spring configuration xml file
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basenames" value="resources/messages"></property>
</bean>
Solution 2 : change in your input element
<form:input type="number" path="freePasses" /> this worked for me try this
In messages.properties file, after the error type, you must to specify the modell attribute (which is in your CustomerController) name, not the class name. So typeMismatch.attribute name.freePasses= Invalid number.

I am a new to Spring boot so I apologize if this is a easily resolved issue.
I am seeing a problem running springboot after I added a #Transient final variable to my entity. Essentially I need a constant variable in my class that stores a string that I do not want stored in the database.
Adding in just this variable causes no issues with spring and the program runs as expected however, if I add a getter for this variable Springboot raises the exception:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.MappingException: Could not get constructor for org.hibernate.persister.entity.SingleTableEntityPersister
Here is my code causing the issue (I am not even calling the getter yet and it's causing this issue):
#ApiModel(description = "This class represents a device with its basic information.")
#Entity
#Table(name = "device")
public class Device {
#Transient
private final String invisibleName = "Jwfqp4bbqiFzRLcFVV3qf";
#Id
#ApiModelProperty(notes = "A UUID number to identify the device in the system.")
private String deviceId;
#ApiModelProperty(notes = "The device IP address of the device, this is also a unique identifier.")
private String ipAddress;
public Device() {
}
#Id
public String getDeviceId() {
return deviceId;
}
public void setDeviceId(String deviceUuid) {
this.deviceId = deviceUuid;
}
public String getIpAddress() {
return ipAddress;
}
public void setIpAddress(String ipAddress) {
this.ipAddress = ipAddress;
}
public String getInvisibleName(){
return invisibleName;
}
}

One important thing that I've noticed is that I can resolve the building issue by adding a useless parameter to the the getter such as:
public String getInvisibleName(int temp){
return invisibleName;
}
but If possible I would like to get to the bottom of this issue so I don't have useless parameters in my getter.
Let me know if I need to provide any additional information.
Thanks
Thank you all for your help. I removed the extraneous #Id on the 'getDeviceId' and moved the #Transient to the getter. I also noticed that apparently Spring had created an 'invisibleName' entry in the database causing a mismatch with my #Entity class. I removed the field from the database and that resolved the issue.
You should move the #Transient annotation above the getInvisibleName() method.
I am trying to start my Spring server but keep getting this error:
Description:

Action:
Consider defining a bean of type 'com.amazonaws.services.s3.AmazonS3' in your configuration.
I have tried:
pasting in the keys as strings right into the BasicAWSCredentials
putting the keys into application.properties and then using #Value to access them. With this approach, I get this error:

Not exactly sure what to do... I am following a tutorial on how to do this and my config pretty much matches this instructor's. Any suggestions?
Your are missing #Bean annotation on public AmazonS3 S3()
#Bean
public AmazonS3 S3() {
AWSCredentials awsCredentials = new BasicAWSCredentials(
AWS_ACCESS_KEY_ID,
AWS_SECRET_ACCESS_KEY
);
return AmazonS3ClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(awsCredentials)).withRegion(Regions.SA_EAST_1).build();
}
Regarding the 2nd issue for properties values, not sure if this the typo here
local.AWS_ACCESS_KEY_ID in logs vs application.AWS_ACCESS_KEY_ID in code sample.
You need to use the same keys name as in your properties file
So you config class should be having
#Value("${AWS_ACCESS_KEY_ID}")
private String AWS_ACCESS_KEY_ID;
#Value("${AWS_SECRET_ACCESS_KEY}")
private String AWS_SECRET_ACCESS_KEY;
The only thing I have done so far is create a package called "controller" with a "HomeController.java" file inside it, with this code:
package com.demo.spring.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
public class HomeController {
#RequestMapping(value = "/", method = RequestMethod.GET)
#ResponseBody
public String index(){
return "Hello World.";
}
}

My file structure:
Full error:
Whitelabel Error Page This application has no explicit mapping for
/error, so you are seeing this as a fallback.
Wed Jan 17 15:17:56 GMT 2018 There was an unexpected error (type=Not
Found, status=404). No message available
If you're returning a raw string like this you should add the #ResponseBody annotation below your other annotation.
Alternatively, you can leave that off and do it like this. This says you're returning a valid HTTP response entity (200 code) with a string, and it will be converted into JSON automatically for you.
#RequestMapping(value = "whatever_path", method = RequestMethod.GET)
public ResponseEntity<String> getResult() {
return new ResponseEntity<>("Hello World", HttpStatus.OK);
}
I had a file missing called DemoSpringApplication.java. It should have been in com.demo.spring package.
This file should have been a default file. I'm not sure if I accidentally removed it or if it was never there. I created a new project inside IntelliJ and it showed in the new project automatically.
See this image compared to the above:
I received such error when 'SpringApplication' class and controller classes are in different packages.
Adding
#SpringBootApplication(scanBasePackages = "a.b.c")
fixed my issue
In my Spring boot application i should show a date string on html. I using this code to get a time jason:
spring:
jackson:
date-format: HH:mm:ss.SSSSSS
joda-date-time-format: HH:mm:ss.SSSSSS
it can be word when i run with IDEA, but it can't work when i use maven to packet a jar and run this jar.
there is exception message :
beans.factory.BeanCreationException: Error creating bean with name 'jacksonObjectMapperBuilder' defined in class path resource [org/springframework/boot/autoconfigure/jackson/JacksonAutoConfiguration$Jac
ksonObjectMapperBuilderConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframe

how should do to get a jason time String?

in my spring boot application i should to return a jason String with TimeData.
it can be get well run with IDEA ,but couldn't run with jar .
This smells like a classpath issue. Your stacktrace also has nothing to do with your actual code. I think you may be pulling in incompatible versions of the same library somehow. Ensure you actually need all those dependencies and see what you can remove and try rerunning your jar.
I generated a project on start.spring.io with the following project dependencies:
Jersey (JAX-RS)
JPA
PostgreSQL
Web
When I try to access localhost:8080/homeroom/webapi/test I get a page with the following error:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
I get this error no matter what url I try to access.
In my console info I can see it print Mapping servlet: 'jerseyServlet' to [/webapi/*] so I know my config class is being registered. When I change #ApplicationPath("/webapi") to #ApplicationPath("/"), a GET on localhost:8080/homeroom/test or localhost:8080/homeroom/ returns a blank page instead, with no text or error.
Why can't I access my resource?

I'm trying to do a descriptor-less deploy so I have:
#Component
#ApplicationPath("/webapi")
public class MyJerseyConfig extends ResourceConfig{
public MyJerseyConfig() {
// String packageName =TestJerseyResource.class.getPackage().getName();
// this.packages(packageName);
this.register(TestJerseyResource.class);
// System.out.println("The package is:"+packageName);
}
}
And I have the following resource:
#Component
#Path("/test")
public class TestJerseyResource {
#GET
#Produces(MediaType.APPLICATION_JSON)
public String getTest()
{
return "Hi!";
}
}
I'm running the project from:
#SpringBootApplication
public class HomeRoomApplication {
public static void main(String[] args) {
SpringApplication.run(HomeRoomApplication.class, args);
}
}
UPDATE:
So 2 things:
I had to use spring annotations #Controller and #RequestMapping instead of Jersey's #PATH and #GET, and had to GET /webapi/test instead of /homeroom/webapi/test
The reason you can't access your resource from looking at the information you provided is you there is no /homeroom anywhere I saw in your code.
This is a valid URL for your project:
http://localhost:8080/webapi/test
If you wanted homeroom to be in the URL you could change the application path value to homeroom instead of webapi.
Well, quoting from #ApplicationPath JavaDoc:
May only be applied to a subclass of Application.
https://docs.oracle.com/javaee/6/api/javax/ws/rs/ApplicationPath.html
That might be part of the problem...
