Grails 全局异常捕获

package middol.global

import grails.converters.JSON

/**

*/
trait GlobalExceptionHandle {

    Result handle(Exception e){
        render ResultUtils.error(e.getMessage()) as JSON
    }
}

然后在controller里面去实现这个接口就可以了

package middol.test


import grails.rest.*
import grails.converters.*
import middol.global.BusinessException
import middol.global.GlobalExceptionHandle

class TestController implements GlobalExceptionHandle{
	static responseFormats = ['json', 'xml']
	
    def index() throws Exception{
        if(true){
            throw new BusinessException("出异常啦")
        }
    }
}
