I am trying to build a project with lombok and this is what I have as dependencie.
dependencies {
compile("org.springframework.boot:spring-boot-starter-thymeleaf")
compile("org.springframework.social:spring-social-facebook")
compile("org.springframework.social:spring-social-twitter")
testCompile("org.springframework.boot:spring-boot-starter-test")
testCompile("junit:junit")
compile("org.springframework.boot:spring-boot-devtools")
compile("org.springframework.boot:spring-boot-starter-data-jpa")
compile("mysql:mysql-connector-java")
compileOnly("org.projectlombok:lombok:1.16.10")
}
I am able to include the anotations, and I have included lombok in the editor. I am even able to compile a code using lombok and making a cal to a method generated by lombok.
This is my entity:
@Data
@Entity
@Table(name = "TEA_USER", uniqueConstraints = {
@UniqueConstraint(columnNames = { "USR_EMAIL" }),
@UniqueConstraint(columnNames = { "USR_NAME" })
})
public class User {
@NotNull
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="USR_ID")
private long id;
@NotNull
@Column(name="USR_FNAME")
private String firstName;
@NotNull
@Column(name="USR_LNAME")
private String lastName;
@NotNull
@Min(5)
@Max(30)
@Column(name="USR_NAME")
private String username;
@Column(name="USR_EMAIL")
private String email;
@Min(8)
@NotNull
@Column(name="USR_PASSWORD")
private String password;
}
And this is a function that compiles fine:
@PostMapping("/registration/register")
public String doRegister (@ModelAttribute @Valid User user, BindingResult result){
user.getEmail();
System.out.println(user.getFirstName());
if (result.hasErrors()) {
return "register/customRegister";
}
this.userRepository.save(user);
return "register/customRegistered";
}
But when I run bootRun and I try to access the funcionality this is the Exception I get:
org.springframework.beans.NotReadablePropertyException: Invalid property 'firstName' of bean class [com.lucasfrossard.entities.User]: Bean property 'firstName' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
But, if I manually include the setter and getters, this works fine. I don't get whats going on and how to fix it. Any idea?
With the latest Lombok 1.18 it's simple. io.franzbecker.gradle-lombok
plugin is not required. Example dependencies from my project:
dependencies {
implementation "org.springframework.boot:spring-boot-starter-thymeleaf"
implementation "org.springframework.social:spring-social-facebook"
implementation "org.springframework.social:spring-social-twitter"
implementation "org.springframework.boot:spring-boot-starter-data-jpa"
testImplementation "org.springframework.boot:spring-boot-starter-test"
runtimeClasspath "org.springframework.boot:spring-boot-devtools"
runtime "mysql:mysql-connector-java"
// https://projectlombok.org
compileOnly 'org.projectlombok:lombok:1.18.4'
annotationProcessor 'org.projectlombok:lombok:1.18.4'
}
Other suggestions:
testCompile("junit:junit")
is not required because the spring-boot-starter-test
“Starter” contains JUnit . implementation
or api
configuration instead of compile
(since Gradle 3.4 ). How do I choose the right one? Do not use compile
configuration for devtools
. A tip from Developer Tools guide:
Flagging the dependency as optional in Maven or using a custom
developmentOnly
configuration in Gradle (as shown above) is a best practice that prevents devtools from being transitively applied to other modules that use your project.
If you use IntelliJ IDEA, make sure you have Lombok plugin installed and Annotation Processing enabled. To make an initial project setup easier for newcomers you can also specify the Lombok plugin as required .
After struggling with this for a while I found this plugin would do the trick:
https://github.com/franzbecker/gradle-lombok
My gradle file just looks like this:
buildscript {
repositories {
maven { url "https://repo.spring.io/libs-milestone" }
maven { url "https://plugins.gradle.org/m2/" }
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.0.RELEASE")
classpath 'org.springframework:springloaded:1.2.6.RELEASE'
}
}
plugins {
id 'io.franzbecker.gradle-lombok' version '1.8'
id 'java'
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
jar {
baseName = 'gs-accessing-facebook'
version = '0.1.0'
}
repositories {
mavenCentral()
maven { url "https://repo.spring.io/libs-milestone" }
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
// compile("org.projectlombok:lombok:1.16.10")
compile("org.springframework.boot:spring-boot-starter-thymeleaf")
compile("org.springframework.social:spring-social-facebook")
compile("org.springframework.social:spring-social-twitter")
testCompile("org.springframework.boot:spring-boot-starter-test")
testCompile("junit:junit")
compile("org.springframework.boot:spring-boot-devtools")
compile("org.springframework.boot:spring-boot-starter-data-jpa")
compile("mysql:mysql-connector-java")
}
idea {
module {
inheritOutputDirs = false
outputDir = file("$buildDir/classes/main/")
}
}
bootRun {
addResources = true
jvmArgs "-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005"
}
I had come across this plugin before but I did something wrong and it didn't work. I am glad it worked now.
Thanks!
If you are using Eclipse
or one of its offshoots(I am using Spring Tool Suite 4.5.1.RELEASE
, - the same steps apply for another other release), all that you need to do is:
In build.gradle
, you ONLY need this configuration:
dependencies { compileOnly 'org.projectlombok:lombok' annotationProcessor 'org.projectlombok:lombok' }
Then, right-click on your project > Gradle > Refresh Gradle Project. The lombok-"version".jar
will appear inside your project's Project and External Dependencies
Right-click on that lombok-"version".jar
> Run As > Java Application (similar to double-clicking on the actual jar or running java -jar lombok-"version".jar
on the command line.)
A GUI will appear, follow all the instructions and one of the thing it does is, it copies lombok.jar
to your IDE's root folder.
The only other thing you will need to do, is to add that lombok.jar
to your project build/class path.
That's it, cheers!
