How to configure CXF servlet in Springboot 2.1.1 Final? - apache

PLease find the error I am facing :
In springboot 2.1.1 I am getting below error :
APPLICATION FAILED TO START
Description: Parameter 1 of constructor in
org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration
required a bean of type
'org.springframework.boot.autoconfigure.web.servlet.DispatcherServletPath'
that could not be found.
The following candidates were found but could not be injected:
- Bean method 'dispatcherServletRegistration' in 'DispatcherServletAutoConfiguration.DispatcherServletRegistrationConfiguration'
not loaded because DispatcherServlet Registration found non dispatcher
servlet dispatcherServlet
Action:
Consider revisiting the entries above or defining a bean of type
'org.springframework.boot.autoconfigure.web.servlet.DispatcherServletPath'
in your configuration.
My configuration:
#Configuration
public class CXFConfig {
#Bean
public ServletRegistrationBean dispatcherServlet() {
final ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new CXFCdiServlet(), "/services/*");
servletRegistrationBean.setLoadOnStartup(1);
return servletRegistrationBean;
}
#Bean(name = Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
SpringBus springBus = new SpringBus();
springBus.getInInterceptors().add(new AppInboundInterceptor());
springBus.getOutInterceptors().add(new AppOutboundInterceptor());
return springBus;
}
}
Please confirm how to do the configuration?
dispatcherServlet() method doesn't work in Springboot 2.1.1

I solved this problem by change the method name from dispatcherServlet to disServlet.
Maybe you can try.

spring gateway unable to start with feign client

Using Spring 2.7.0 to create an API gateway, that was working fine until I tried to replace the RestTemplate with OpenFeign.
Here is the relevant build.gradle contents:

}
My FeignClient:

public interface IdentityServiceClient {
#GetMapping("/api/all")
public List<ApiKey> getAllApiKeys();
}
when I try to start the application now I get:

Action:
Consider defining a bean of type 'org.springframework.boot.autoconfigure.http.HttpMessageConverters' in your configuration.
But none of the online examples seem to show the need for adding custom HttpMessageConverters since they are included in spring-web and spring-boot-starter-webflux
UPDATE -
this appears to be related to #Autowired. I put both my service and feign service in a regular class and it starts up fine. But when I autowire those two services, I get this error again.

spring data elasticsearch Invocation of init method failed; nested exception is java.lang.AbstractMethodError

I have problem with Spring Data Elasticsearch. I configure elasticsearch like this:
#Configuration
#EnableJpaRepositories(basePackages = {"org.project.repositories"})
#EnableElasticsearchRepositories(basePackages = "org.project.repositorieselastic")
#EnableTransactionManagement
public class PersistenceContext {
#Bean
public ElasticsearchOperations elasticsearchTemplate() {
return new ElasticsearchTemplate(client());
}
#Bean
public Client client(){
Settings settings = ImmutableSettings.settingsBuilder()
// Setting "transport.type" enables this module:
.put("cluster.name", "elasticsearch")
.put("client.transport.ignore_cluster_name", false)
.build();
TransportClient client= new TransportClient(settings);
TransportAddress address = new InetSocketTransportAddress("127.0.0.1", 9300);
client.addTransportAddress(address);
return client;
}
}
My repo looks like.
#Repository()
public interface UserFavoriteElasticRepo extends ElasticsearchRepository<UserFavorite, Long> {
}
Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: org.project.repositorieselastic.UserFavoriteElasticRepo org.project.services.elastic.FavoriteIndexerService.elasticRepo; nested exception
is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userFavoriteElasticRepo': Invocation of init method failed; nested exception is java.lang.AbstractMethodError
It's look like the implementation is not generated. But I don't know where to investigate. I tried to use one package and use this - https://github.com/izeye/spring-boot-throwaway-branches/commit/874ccba09189d6ef897bc430c43b6e3705404399 but with no success.
I solved the problem adding this in pom file
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-commons</artifactId>
<version>1.12.2.RELEASE</version>
</dependency>
I've got same exception using spring-data-elasticsearch.
But exception was thrown when I declared new methods in repository:
ex.:
public interface UserFavoriteElasticRepo extends ElasticsearchRepository<UserFavorite, Long> {
Page<UserFavorite> findBySomeProperty(String propertyValue, Pageable pageable);
}
It was casued due to spring-data-elasticsearch, spring-data-commons versions. Function declarations have changed: org.springframework.data.repository.query.QueryLookupStrategy.resolveQuery - it caused the exception.
For spring-data-elasticsearch version 2.0.0.RELEASE you have to use spring-data-commons with version 1.12.0.
If you have spring-data-jpa in your project it also uses spring-data-commons. For spring-data-jpa v1.9.0.RELEASE, spring-data-commons is v1.11.0.RELEASE
Could you provide what frameworks and versions of spring you are using? Also If you could put whole stacktrace, it will be helpfull?

Spring Boot ignore ObjectMapper module

In application context I have registered an ObjectMapper module:
#Bean
public SimpleModule jsr310Module() {
final SimpleModule module = new SimpleModule();
module.addSerializer(new LocalDateSerializer());
module.addDeserializer(LocalDate.class, new LocalDateDeserializer());
return module;
}
I tried to debug and it is loaded (or at least the method public void setupModule(SetupContext context) is execute on boot)
but when I call a rest API that return an object with a LocalDate my deserializer is ignored.
Some hint to solve the problem?
To make it work the #Configuration class should extend WebMvcAutoConfiguration
According to the Spring Boot documentation, to configure the ObjectMapper you can either define the bean yourself and annotate it with #Beanand #Primary. There you can register the module. Or you can add a bean of type Jackson2ObjectMapperBuilderwhere you can customize the ObjectMapper.

#BeanParam does not work with Apache CXF 3.0.x

I am trying to use #BeanParam annotation from JAX-RS.
It was working perfectly fine with Apache cxf 2.7.7 but after upgrading to Apache cxf 3.0.1 it does not work. In my rest service, bean param is null and i get NullPointerException.
I have tried with cxf 3.0.3 but result is same.
My RestService looks like
Class MyService {
#BeanParam
private MyBean params;
#Path("/test")
public Response testIt() {
// params is null here
}
}
class MyBean {
#QueryParam
private String message;
public void setMessage(String message) {
this.message = message;
}
public String getMessage() {
return this.message;
}
}
My dependency in gradle looks like
def cxfVersion = "3.0.1"
ext.libraries = [
cxf: [
"org.apache.cxf:apache-cxf:$cxfVersion",
"org.apache.cxf:cxf-rt-frontend-jaxrs:$cxfVersion"
]
Does anybody have any idea what has changed form cxf 2.7.7 to cxf 3.0.x, that will make this non functioning.
I found the problem. It was due to presence of another cxf version jar present on classpath (version 2.3.3) coming from other projects dependencies. Somehow that was getting the precedence over 3.x version and that didn't had support for BeanParam.
Removing that jar from classpath worked for me.

Spring boot JNDI datasource lookup failure - Name comp/env/jdbc not found in context "java:"

I have setup a spring boot (v 1.1.9) application to deploy as a WAR file. And I'm trying to integrate this web application with an existing data service module (added as a maven dependency).
Environment trying to deploy: WebSphere Application Server 8.5.5.4
The issue I'm facing is an application start-up failure when try to look-up a JNDI dataSource (jdbc/fileUploadDS) as below within the dependent data service module.
#Configuration
#Profile("prod")
public class JndiDataConfig implements DataConfig {
#Bean
public DataSource dataSource() throws NamingException {
Context ctx = new InitialContext();
return (DataSource) ctx.lookup("java:comp/env/jdbc/fileUploadDS");
}
}
My Spring Boot configuration:
#Configuration
#ComponentScan(basePackages = { "au.com.aiaa.fileupload.data.*", "demo" })
#EnableAutoConfiguration(exclude = { HibernateJpaAutoConfiguration.class, DataSourceAutoConfiguration.class })
public class SampleApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(applicationClass, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(applicationClass);
}
private static Class<SampleApplication> applicationClass = SampleApplication.class;
#Bean
public static Properties fileUploadJndiProperties() throws NamingException {
JndiObjectFactoryBean jndiFactoryBean = new JndiObjectFactoryBean();
jndiFactoryBean.setJndiName("props/FileUploadProperties");
jndiFactoryBean.setExpectedType(Properties.class);
jndiFactoryBean.setLookupOnStartup(true);
jndiFactoryBean.afterPropertiesSet();
return (Properties) jndiFactoryBean.getObject();
}
}
Note that I'm able to lookup props/FileUploadProperties successfully. But failing to do the same for a datasource.
My doubt is it is trying to load a EmbeddedWebApplicationContext which is not what I want.
The stack trace is:
Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public javax.sql.DataSource au.com.aiaa.fileupload.data.dao.configuration.JndiDataConfig.dataSource() throws javax.naming.NamingException] threw exception; nested exception is **javax.naming.NameNotFoundException: Name comp/env/jdbc not found in context "java:".**

What am I missing here? Even when I try to explicitly define the dataSource bean method in SampleApplication.java like below it fails with the same error.
#Bean
public static DataSource dataSource() throws NamingException {
JndiObjectFactoryBean jndiFactoryBean = new JndiObjectFactoryBean();
jndiFactoryBean.setJndiName("java:comp/env/jdbc/fileUploadDS");
jndiFactoryBean.setExpectedType(DataSource.class);
jndiFactoryBean.setLookupOnStartup(true);
jndiFactoryBean.setResourceRef(true);
jndiFactoryBean.afterPropertiesSet();
return (DataSource) jndiFactoryBean.getObject();
}
I referred this and it says we need to set enableNaming() on servlet container? Can I do something similar for non-embedded web application context? Or is it purely a WAS 8.5 issue??
You need to have resource reference with jdbc/fileUploadDS name in your web.xml. And make sure it is bound to actual datasource name during installation or via ibm-web-bnd.xml file.
Definition in web.xml:
<resource-ref>
<description />
<res-ref-name>jdbc/fileUploadDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
If you dont want to use web.xml, then in normal Java EE app you could just add in web component (servlet, filter) the following class annotation:
#Resource(name="jdbc/fileUploadDS", type=javax.sql.DataSource.class, lookup="jdbc/fileUploadDS")
but I'm not Spring-boot expert, so don't know, if it will work or is possible there.
I am able to connect my Spring-Boot application (deployed in Websphere Application Server 9) to WAS datasource.
The following code worked for me, for connecting to DataSource:
#Bean(name = "WASDataSource")
public DataSource WASDataSource() throws Exception {
JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
return dataSourceLookup.getDataSource("DSNAME");
}
#Bean(name = "WASDataSourceJdbcTemplate")
public JdbcTemplate jdbcTemplate_WASDS(#Qualifier("WASDataSource")
DataSource dsDB2) {
return new JdbcTemplate(dsDB2);
}
Note: The name of Datasource "DSNAME" is the name which appears on the UI of Websphere console.
You can see that via -> Select Resources > JDBC > Data Sources.
Then I created jdbc template:
#Autowired
#Qualifier("WASDataSourceJdbcTemplate")
private JdbcTemplate db2WASTemplate;`
And running query using the query method works fine :
db2WASTemplate.query()
I did not create any Web.xml or ibm-web-bnd.xml files
I just configured spring boot with my custom datasource as follows:
#Bean
#ConfigurationProperties("spring.datasource")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
and inside the application.properties file I defined all datasource settings as usual
spring.datasource.driver-class-name= ***
spring.datasource.url= ***
spring.datasource.username= ***
spring.datasource.password= ***
spring.datasource.jndi-name=jdbc/myDB
It works nicely with #SpringBootApplication with all other default settings
I am facing the same problem. I don't know how to define tag in spring boot since there is no web.xml file in the spring boot.
So far what I came to know that we have to define it in the application file from where we start our spring application. I think we need to use this method to set the Datasource:
#Bean(destroyMethod="")
#ConfigurationProperties(prefix="datasource.mine")
public DataSource dataSource() throws Exception {
JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
return dataSourceLookup.getDataSource("java:jdbc/configurationFile");
}
