thymeleaf 语法 th:style 里多个判断条件

正确 语法是
th:style="${bingMoshi=='hei'?'color:#f8f8f2;':'color:#3e3e3e;'} + ${bingFontSize != null ?'font-size:'+ bingFontSize +';':''} + ${bingLineHeight != null ?'line-height:' + bingLineHeight+';':''}"

 

下面这种写法是错误的
th:style="${bingMoshi=='hei'}?'color:#f8f8f2;':'color:#3e3e3e;' + ${bingFontSize != null} ?'font-size:'+ ${bingFontSize}+';':'' + ${bingLineHeight != null} ?'line-height:' + ${bingLineHeight}+';':'' "
