Can't generate aspectOf() method wih gradle plugin.
My AspectJ config class and some aspect class:
#Aspect
public class SendToAspect {
#Around("execution (public * *(..)) && #annotation(ann)")
public Object execute(final ProceedingJoinPoint point, final SendTo ann) throws Throwable {
return point.proceed();
}
}
#Configuration
#EnableAspectJAutoProxy
public class AspectjConfiguration {
#Bean
public SendToAspect sendToAspect() {
return Aspects.aspectOf(SendToAspect.class);
}
}

}
}
After building and running my springBoot app I get the same error:
error creating bean with name 'sendToAspect' defined in class path resource
[com/example/config/aspectj/AspectjConfiguration.class]: Bean instantiation via factory method failed;
nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.example.utils.aop.SendToAspect]:
Factory method 'sendToAspect' threw exception; nested exception is org.aspectj.lang.NoAspectBoundException:
Exception while initializing com.restaurantclub.soa.utils.aop.SendToAspect: java.lang.NoSuchMethodException: com.restaurantclub.soa.utils.aop.SendToAspect.aspectOf()
What needs to be done or which plugin should i use to work?
My Gradle version: 5.2.1
Solution - just use 'io.freefair.aspectj.post-compile-weaving' instead io.freefair.aspectj.base

I am doing a Java / Spring course. Here is the code:
package com.pinodev.helloServer;
import reactor.netty.http.server.HttpServer;
public class HelloServerApplication {
public static void main(String[] args) {
HttpServer server = HttpServer.create("localhost",8080);
}
}
build.gradle:
plugins {
id 'org.springframework.boot' version '2.4.2'
id 'io.spring.dependency-management' version '1.0.11.RELEASE'
id 'java'
}
group = 'com.pinodev'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'
repositories {
mavenCentral()
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-webflux'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'io.projectreactor:reactor-test'
}
test {
useJUnitPlatform()
}
This is where the error occurs
error: 'create()' in 'reactor.netty.http.server.HttpServer' cannot be applied to '(java.lang.String, int)'
You should create the server as follows:
HttpServer.create()
.host("0.0.0.0")
.port(8080)
.handle((req, res) -> res.sendString(Flux.just("hello")))
.bind()
.block();
The method create() is the only one available in HttpServer. The create with two parameters must have existed in a previous version.
class HttpServer doesn't have parameters in create() method, for setting it you should use builder method for example:
HttpServer.create()
.host("127.0.0.1")
.port(8080)
.handle((req, res) -> res.sendString(Flux.just("hello")))
.bind()
.block();

Can Anyone please tell me what am I doing wrong?
Thanks!
You need to create beans of MongoTemplate since there are none to be injected by default configuration.
#Bean
public MongoClient mongoClient() {
return new MongoClient("localhost", 27017);
}
#Bean
public MongoTemplate mongoTemplate(MongoClient mongoClient) throws Exception {
return new MongoTemplate(mongoClient, "databaseName");
}
Also, don't forget to use com.mongodb.client.MongoClient which replaces reprecated com.mongodb.MongoClient as of Spring Boot 2.2.
When I try to compile/build a Spring Boot project with Spark/Phoenix dependencies, it says there's too many SLF4J's, and when i try to exclude a package, it throws the above error.
How can i get them to work together?

Project was generated via start.spring.io site.
After some tests, I've found out my problem. That was an NPE exception in init method of my bean annotated with #PostConstruct. You can reproduce this issue like this:
#Component
class Test {
String str;
#PostConstruct
private void init() {
System.out.println(str.length());
}
}
I don't understand why spring throws so unclear exception.
I'm trying to deploy a war generated with springboot in Tomcat, in which I have succeeded previously, but can't figure out what is wrong this time.
The most important code is added:

#EnableTransactionManagement
#Component
//#EnableWebMvc
#ComponentScan("com.singleuseapps")
public class AppConfig {
LaptopsApplication
#SpringBootApplication
#ComponentScan(basePackageClasses = {AppConfig.class,LaptopsApplication.class})
public class LaptopsApplication extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(LaptopsApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(LaptopsApplication.class, args);

You should:
remove #Component from AppConfig (it's already annotated with #Configuration)
remove .configure method from LaptopsApplication, it's already annotated with #SpringBootApplication and is automatically a configuration class you don't need to add it again
Ensure your controller class is in the package specified by your two #ComponentScan annotations (you probably just need the one on your main app class)
