Question

这个例子很有效，我认为唯一改变的是我安装的java和groovy的版本。

@Grab('org.springframework:spring-context:3.2.1.RELEASE')
@Grab('org.apache.commons:commons-lang3:3.1')
@GrabConfig(systemClassLoader = true)
import org.springframework.context.support.ClassPathXmlApplicationContext

def ctx = new ClassPathXmlApplicationContext("classpath:context.xml")
def su = ctx.getBean('su')
def result = su.swapCase('Fee Fi Fo Fum') 
assert result == 'fEE fI fO fUM'
println "result = $result"

这是context.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
   <bean id="su" class="org.apache.commons.lang3.StringUtils"/>
   <bean id="data" class="java.lang.String"><constructor-arg   value="Fee Fi Fo Fum"/></bean>
</beans>

如果我注释掉它运行的上下文文件的最后一行的第二行。

这曾经起作用，现在不起作用。我现在在做什么？

我正在跑步

Groovy 2.3.0-beta-2

至少需要Spring 4才能使用Java 8进行编译。

在此宣布：http://docs.spring.io/spring/docs/current/spring-framework-reference/html/new-in-4.0.html

您使用的是Spring 3.2，您必须使用Java 7。

使用Groovy对字符串进行弹簧注入
