                    <artifactId>maven-compiler-plugin</artifactId>
                    <configuration>
                        <source>1.8</source>
                        <target>1.8</target>
                        <encoding>UTF-8</encoding>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>

 

安装lombok插件： 

1. 下载 https://plugins.jetbrains.com/plugin/6317-lombok-plugin

2.  Setting -> plugins ->install plugin from disk 

3.  Setting->Build,Exe... -> Compiler->Annotation Processors -> 勾选enable annotation processing

遇到的问题：

1.  The parameters ‘encoding‘ for goal org.projectlombok:lombok-maven-plugin:1.16.16.0:delombok are missing or invalid

根据 ， 缺少encoding参数 在pom中添加如下属性：

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

2. 添加@Data注解后，根据注解生成的方法没有在outline中显示， 以及无法在代码编辑是resolve注解生成的方法

解决： 添加lombok-plugin
