java - Apache Velocity 无法初始化

Question

当我尝试使用初始化速度引擎时

VelocityEngine engine = new VelocityEngine();
engine.init();

当我尝试时遇到同样的错误

Velocity.init();

org.apache.velocity.exception.VelocityException: Failed to initialize an instance of org.apache.velocity.runtime.log.ServletLogChute with the current runtime configuration.

什么可能导致此异常？

Answer 1

尝试这样的事情:

Properties p = new Properties();
p.setProperty("resource.loader", "class");
p.setProperty("class.resource.loader.description", "Velocity Classpath Resource Loader");
p.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");

    try {
      Velocity.init(p);
    } catch(...., and handle excpetion
  }

您现在可以调用:

VelocityContext vContext = new VelocityContext(context);
//put things into vContext
StringWriter sw = new StringWriter();
    try {
      template.merge(vContext, sw);

等等
