SpringTemplateEngine setRenderHiddenMarkersBeforeCheckboxes method did not exist - spring-boot

I am creating a web application with SpringBoot and Thymeleaf layouts. Once I start the application, I get the following error while using Thymeleaf.
The following method did not exist:
org.thymeleaf.spring5.SpringTemplateEngine.setRenderHiddenMarkersBeforeCheckboxes(Z)V
My POM :
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.0.RELEASE</version>
</parent>
<properties>
<java.version>1.8</java.version>

<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>nz.net.ultraq.thymeleaf</groupId>
<artifactId>thymeleaf-layout-dialect</artifactId>
</dependency>
Java Config :
#Bean
public LayoutDialect layoutDialect() {
return new LayoutDialect();
}
Any idea?

Turned out to be a version issue. Solved it by changing the thymeleaf.version to thymeleaf-spring5.version in properties
<properties>
<java.version>1.8</java.version>
<!--<thymeleaf.version>3.0.9.RELEASE</thymeleaf.version>-->
<thymeleaf-spring5.version>3.0.9.RELEASE</thymeleaf-spring5.version>
<thymeleaf-layout-dialect.version>2.4.1</thymeleaf-layout-dialect.version>

Spring Boot: Unable to look up data source

I'm running an application framework (jbpm) on Spring Boot which requires looking up a Datasource.
I'm facing the following error:
java.lang.RuntimeException: Unable to look up data source: java:jboss/datasources/ExampleDS - Need to specify class name in environment or system property, or in an application resource file: java.naming.factory.initial
at org.jbpm.process.workitem.executesql.ExecuteSqlWorkItemHandler.<init>(ExecuteSqlWorkItemHandler.java:83) ~[execute-sql-workitem-7.52.0.Final.jar:7.52.0.Final]
at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) ~[na:na]
I have got the following properties in application.properties:
spring.datasource.username=sa
spring.datasource.password=sa
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driver-class-name=org.h2.Driver
#hibernate configuration
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.H2Dialect
I have also added in my configuration class the following:
#Bean
public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
bean.setJndiName("java:jboss/datasources/ExampleDS");
bean.setProxyInterface(DataSource.class);
bean.setLookupOnStartup(false);
bean.afterPropertiesSet();
return (DataSource) bean.getObject();
}
I have checked the code of the jbpm handler:
https://github.com/kiegroup/jbpm-work-items/blob/main/execute-sql-workitem/src/main/java/org/jbpm/process/workitem/executesql/ExecuteSqlWorkItemHandler.java#L79
I see this is the code which does the lookup:
this.ds = InitialContext.doLookup(dataSourceName);
What am I missing in my code/configuration?
Thanks

Use RouterFunction with embedded Eureka server

I'm having an issue getting a simple web app using Spring Reactive's RouterFunction to work with an embedded Eureka server. I tried a couple of things, including using the old way of annotating #RestController which works fine. Furthermore, I tried to removing the Eureka dependency from the POM file after which the RouterFunction endpoint worked fine.

Router, that does not get hit:
#Configuration
public class Router {
#Bean
public RouterFunction<ServerResponse> route(Handler handler) {
return route(GET("/test"), Handler::handle);
}
}
Controller, that get's hit fine:
#RestController
#ResponseStatus(HttpStatus.OK)
public class controller {
#GetMapping("/discovery")
public String getApplication() {
return "test2222";
}
}
Main:
#SpringBootApplication
#EnableEurekaServer
public class DiscoveryApp {
public static void main(String[] args) {
SpringApplication.run(com.test.tds.DiscoveryApp.class, args);
}
}
As stated above, after removing the dependency to Eureka the RouterFunction endpoint works fine.
Does anyone have an idea how to make this work?
Apparently Webflux is currently not supported by Eureka server. It is suggested to use the old spring-boot-starter-web way.

jackson-data-format doesn't convert when using with restTemplate getforObject()

This question is related to [Rest template getForObject() mapping only camel case fields
Having a rest web service that returns the below xml response.
<Person>
<ttId>1408</ttId>
<FirstName>RAJ</FirstName>
<NationalityValue>INDIAN</NationalityValue>
<Sex>Male</Sex>
</Person>
This is the dto
import java.io.Serializable;
import java.util.Date;
public class PersonInfoDto implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private Long ttId;
private String NationalityValue;
private String Sex;
private String FirstName;
//getters and setters
}
Using Spring Boot, When I try to consume using code it returns only one value(which is in camel case). Do I need to add any Naming strategy to make it work ?
String uri = apiPath;
RestTemplate restTemplate = new RestTemplate();
PersonInfoDto personInfoDto = restTemplate.getForObject(uri, PersonInfoDto.class);
//Here the object will contain only one value
ttId = 1408
rest values are returns null.

When I removed the below entry from it worked.

But to map the RequestBody with XML data this dependency is required.
How can I solve this, which converter does rest template is using ? Can I force rest template to use a particular converter. ?
Hi Try adding #XmlRootElement on the PersonInfoDto class. And try once in web browser giving the URI which you are passing.

Spring-boot scheduler runs without #EnableScheduling annotation

I was following this example to create a scheduled task in a sample project: https://spring.io/guides/gs/scheduling-tasks
It says, #EnableScheduling ensures that a background task executor is created. Without it, nothing gets scheduled.
But, by mistake i didn't use it. How come it still works?

Other Classes:
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
#Component
public class ScheduledTaskRunner {
Logger log = LoggerFactory.getLogger(ScheduledTaskRunner.class);
#Scheduled(cron = "0/1 * * * * *")
public void run(){
log.info("Hello");
}
}
Isn't the scheduled task supposed to not run?
Your code added the spring-boot-starter-actuator when that is added a scheduler is added as well. This scheduler is used by the actuator to schedule the automatic export of the metrics.
The code for this is in the MetricExportAutoConfiguration and has been added in Spring Boot 1.3.0.
So if you remove the actuator scheduling won't work anymore.

SpringBootApplication cannot be resolved to a type

Hi below is my Spring code and pom.xml. Maven is not able to update even though I tried to force project update. Any resolution on this or direction where I am getting wrong.
package com.boot;
import org.springframework.*;
#SpringBootApplication
public class App
{
public static void main( String[] args )
{
System.out.println("Hello World");
}
}

I am not getting why Maven is not able to get the dependencies for my project. A
I faced the same issue.
I changed the version from 2.0.5.RELEASE to 2.0.3.RELEASE to make it work
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
If you are fine to move to 2.x then please follow below steps:
Step 1 copy below pom
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.boot</groupId>
<artifactId>das-boot</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>das-boot</name>
<description>Demo project for Spring Boot</description>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.5.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>

<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
Step 2: Here is your main application class:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class DasBootApplication {
public static void main(String[] args) {
SpringApplication.run(DasBootApplication.class, args);
}
}
or you can also stay with 1.4.2, just change java version to 1.6.
You should provide the class name in the run() method like below:
#SpringBootApplication
public static void main(String[] args) {
SpringApplication.run(App.class, args);
Sytem.out.print("Started");
}
And remove the below line from pom.xml
<start-class>com.boot.App</start-class>
