话不多说，先上图：
IDEA安装lombok插件
-
IntelliJ IDEA
- 定位到 File > Settings > Plugins
- 点击 Browse repositories…
- 搜索 Lombok Plugin
- 点击 Install plugin
- 重启 IDEA
Spring Boot项目中使用lombok
- 添加lombok依赖
<!-- lombok代码简化 -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.16</version>
<scope>provided</scope>
</dependency>
- 编写一个实体类进行测试
@Data
public class ConfigBean {
private String name;
private String think;
}
- 编写一个控制类进行访问测试
@RequestMapping(path = "/properties", method = RequestMethod.GET)
public String configProperties() {
return configBean.getName() + ":" + configBean.getThink();
}
lombok 支持的注解：
valFinally! Hassle-free final local variables.
@NonNullor: How I learned to stop worrying and love the NullPointerException.
@CleanupAutomatic resource management: Call your
close()methods safely with no hassle.
@Getter/@SetterNever write
public int getFoo() {return foo;}again.
@ToStringNo need to start a debugger to see your fields: Just let lombok generate a
toStringfor you!
@EqualsAndHashCodeEquality made easy: Generates
hashCodeandequalsimplementations from the fields of your object..
@NoArgsConstructor, @RequiredArgsConstructor and @AllArgsConstructorConstructors made to order: Generates constructors that take no arguments, one argument per final / non-nullfield, or one argument for every field.
@DataAll together now: A shortcut for
@ToString,@EqualsAndHashCode,@Getteron all fields, and@Setteron all non-final fields, and@RequiredArgsConstructor!
@ValueImmutable classes made very easy.
@Builder... and Bob's your uncle: No-hassle fancy-pants APIs for object creation!
@SneakyThrowsTo boldly throw checked exceptions where no one has thrown them before!
@Synchronized
synchronizeddone right: Don't expose your locks.
@Getter(lazy=true)Laziness is a virtue!
@LogCaptain's Log, stardate 24435.7: "What was that line again?"
