## 一、设置模板 ##

### 1、添加模板 ###

**点击Settings -> Templates -> + -> New template name**

### 2、添加模板内容 ###

**（1）生成JSON串**

public java.lang.String toString() {
    final java.lang.StringBuilder sb = new java.lang.StringBuilder("{");
    #set ($i = 0)
    #foreach ($member in $members)#if ($i == 0)
    sb.append("#####
    #else
    sb.append(",####
    #end#if ($member.string || $member.date)
    \"$member.name\":\"")
    #else
    \"$member.name\":")
    #end#if ($member.primitiveArray || $member.objectArray)
    .append(java.util.Arrays.toString($member.name));
    #elseif ($member.string || $member.date)
    .append($member.accessor).append('\"');
    #else
    .append($member.accessor);
    #end#set ($i = $i + 1)
    #end
    sb.append('}');
    return sb.toString();
    }

**（2）生成字符串**

public java.lang.String toString() {
    StringBuilder sb = new StringBuilder();
    sb.append(getClass().getSimpleName());
    sb.append(" [");
    #set ($i = 0)
    #foreach ($member in $members)
    #if ($i == 0)
    #if ($member.primitiveArray || $member.objectArray)
    sb.append("$member.name=").append(java.util.Arrays.toString($member.name));
    #else
    sb.append("$member.name=").append($member.accessor);
    #end
    #else
    #if ($member.primitiveArray || $member.objectArray)
    sb.append(", $member.name=").append(java.util.Arrays.toString($member.name));
    #else
    sb.append(", $member.name=").append($member.accessor);
    #end
    #end
    #set ($i = $i + 1)
    #end
    sb.append(']');
    return sb.toString();
    }

**注：如果本类继承了父类，想带父类属性，需要添加下面代码**

#if ( $class.hasSuper )
    sb.append(super.toString());
    #end

## 二、使用 ##

### 直接点击ok ###
