### 一、自定义自动生成setter方法的格式：生成的set方法，属性赋值后都返回对象本身 ###

例如选择get 、set

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2R5X21hYw_size_16_color_FFFFFF_t_70 1][]

效果是这样子的

代码：

#set($paramName = $helper.getParamName($field, $project))
    #if($field.modifierStatic)
    static ##
    #end
    $classname set$StringUtil.capitalizeWithJavaBeanConvention(
    $StringUtil.sanitizeJavaIdentifier($helper.getPropertyName($field, $project)))($field.type $paramName) {
    #if ($field.name == $paramName)
        #if (!$field.modifierStatic)
        this.##
        #else
            $classname.##
        #end
    #end
    $field.name = $paramName;
    return this;
    }

### 二、自定义toString方法 ###

选择toString后来到这个页面

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2R5X21hYw_size_16_color_FFFFFF_t_70 5][]

效果

代码：

public java.lang.String toString() {
    return org.apache.commons.lang3.builder.ToStringBuilder.reflectionToString(
    this, org.apache.commons.lang3.builder.ToStringStyle.JSON_STYLE);
    }
