Intellij-插件安装-安装CodeGenerator插件并且添加Builder模板

Intellij IDEA 2018.1.2版本

CodeGenerator插件地址:https://github.com/lotabout/CodeGenerator/releases

步骤一：安装插件

　　下载CodeGenerator.jar到本地磁盘，打开Intellij安装插件的界面进行安装

　　

步骤二：添加Builder模式的模板

　　

## Tutorial for writing your templates
##
## 1. First you need to know basic syntax of velocity[1].
## 2. Then it is necessary to understand the variable that CodeGenerator provides
##    and its inner structure for retrieving the information you need for generating code.
## 3. Learn to use the utils provided so that you can ask for further information
##    or reduce your workload.
##
## Variables Provided (Class Mode)

##   - constant: boolean
##   - modifierTransient: boolean
##   - modifierVolatile: boolean
##   - enum: boolean
##   - matchName(String): bool
##
## - MethodEntry
##   - methodName: String
##   - fieldName: String
##   - modifierAbstract: boolean
##   - modifierSynchronzied: boolean
##   - modifierSynchronized: boolean
##   - returnTypeVoid: boolean
##   - getter: boolean
##   - deprecated: boolean
##   - matchName(String): bool
##
## Variables for Body Mode
## -----------------------
## - class0: ClassEntry         The current class
## - fields: List<FieldEntry>   All selected fields
## - methods: List<MethodEntry> All selected methods
## - members: List<MemberEntry> selected fields+methods
## - parentMethod: MethodEntry  The nearest method that surround the current cursor
##
## Utilities
## ---------
## - settings: CodeStyleSettings settings of code style
## - project: Project            The project instance, normally used by Psi related utilities
## - helper: GenerationHelper
## - StringUtil: Class
## - NameUtil: Class
## - PsiShortNamesCache: Class   utility to search classes
## - PsiJavaPsiFacade: Class     Java specific utility to search classes
## - GlobalSearchScope: Class    class to create search scopes, used by above utilities
## - EntryFactory: Class         EntryFactory.of(...) to turn PsiXXX to XXXEntry.
##
## Other feature
## -------------
## - Auto import.      If the generated code contains full qualified name, Code Generator will try to
##                     import the packages automatically and shorten the name.
##                     For example `java.util.List<>` -> `List<>`

public static class Builder {
private ${class0.name} instance = new ${class0.name}();

private Builder() {}

public static Builder getInstance() {
return new Builder();
}
public static Builder getInstance(${class0.name} instance) {
            Builder builder = new Builder();
            builder.instance = instance;
            return builder;
        }
#if ( $members.size() > 0 )
    #foreach( $member in $members )
    #set($name = $StringUtil.capitalizeWithJavaBeanConvention($StringUtil.sanitizeJavaIdentifier($helper.getPropertyName($member.element, $project))))
    public Builder add${name}(${member.type} ${member.accessor}) {
    this.instance.set${name}(${member.accessor});
    return this;
    }
    #end
#end
public ${class0.name} build() {
return this.instance;
}
}
