IDEA toString Json Template

以下连个模板有个不好的地方是有大片的空格，一般手动删，后面有时间研究下这个模板，优化一下

JSON toString() template

Below is a toString() template that print object to a valid JSON. It doesn’t include super.toString() method if current class has superclass.

public java.lang.String toString() {
#if ( $members.size() > 0 )
    #set ( $i = 0 )
return "{\"$classname\":{"
    #foreach( $member in $members )
        #if ( $i == 0 )
        + "##
        #else
        + ", ##
        #end
        #if ( $member.array )
        \"$member.name\":" + java.util.Arrays.toString($member.accessor)
        #elseif ( $member.string || $member.primitive || $member.numeric || $member.boolean || $member.enum )
        \"$member.name\":\"" + $member.accessor + "\""
        #else
        \"$member.name\":" + $member.accessor
        #end
        #set ( $i = $i + 1 )
    #end
+ "}}";
#else
return "{$classname}";
#end
}

JSON toString() template with super.toString() included

Below is a toString() template that print object to a valid JSON. It includes super.toString() method only if current class has super class.

public java.lang.String toString() {
#if ( $members.size() > 0 )
    #set ( $i = 0 )
    #if ( $class.hasSuper )
        #set ( $i = $i + 1 )
    return "{\"$classname\":"
    + super.toString()
    #else
    return "{\"$classname\":{"
    #end
    #foreach( $member in $members )
        #if ( $i == 0 )
        + "##
        #else
        + ", ##
        #end
        #if ( $member.array )
        \"$member.name\":" + java.util.Arrays.toString($member.accessor)
        #elseif ( $member.string || $member.primitive || $member.numeric || $member.boolean || $member.enum )
        \"$member.name\":\"" + $member.accessor + "\""
        #else
        \"$member.name\":" + $member.accessor
        #end
        #set ( $i = $i + 1 )
    #end
    #if ( $class.hasSuper )
    + "}";
    #else
    + "}}";
    #end
#else
return "{$classname}";
#end
}
