How do I use JSTL to output a value from a JSON string?

由 二次信任 提交于 2019-12-19 10:14:19
问题 I’m using JBoss 7.1.3.As.Final and am building a Spring 3.2.11.RELEASE web application. On my JSP page I have this ${jsonString} and what I would like to know is assuming this json string has an attribute “name”, how do I use JSTL (preferably no scriptlets) to print out the value associated with the “name” attribute to my page? Unsurprisingly, this doesn’t work ${jsonString[‘name’]} 回答1: If you can use third party libraries (e.g. Jackson), it should be fairly simple to accomplish this

Whats the difference between “${foo.bar}” and “#{foo.bar}”?

由 落花浮王杯 提交于 2019-12-19 09:06:05
问题 I can use objects from my Java Beans within .jsp files by using the Expression Language (EL). Therefore I can get my value by typing ${foo.bar}. But I can also use #{foo.bar}. Can anybody explain the difference or provide a link with meaningful information? 回答1: #{foo.bar} syntax is from the JSF expression language. Some bright spark thought it would be a good idea to use a different syntax to JSP EL (i.e. ${foo.bar} ). I think some JSP containers are tolerant of this cockup, and let you use
