现在要模板引擎Freemarker整合进springboot。使用freemarker视图解析。
pom文件添加依赖
<!– https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-freemarker –>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
配置freemarker参数，将参数加到application.properties配置文件。
#配置freemarker参数
#设定ftl文件路径
#spring.freemarker.template-loader-path=classpath:/templates/
##设定静态文件路径，js,css等
spring.mvc.static-path-pattern=/static/**
spring.freemarker.cache=false
spring.freemarker.charset=UTF-8
spring.freemarker.check-template-location=true
spring.freemarker.content-type=text/html
spring.freemarker.expose-request-attributes=true
spring.freemarker.expose-session-attributes=true
spring.freemarker.request-context-attribute=request
spring.freemarker.suffix=.ftl
spring.freemarker.template-loader-path=classpath:/templates/
#comma-separated list
#spring.freemarker.view-names= # whitelist of view names that can be resolved
写入控制层，路由映射到模板文件
@Controller
public class LoginController {
@RequestMapping(“/login”)
public String login() {
return “sysLogin”;
}
}
定义freemarker模板,以登录页为样例。
<#assign webRoot=request.contextPath />
<!DOCTYPE html>
<html lang=“en”>
<head>
<meta charset=“utf-8”>
<meta http-equiv=“X-UA-Compatible” content=“IE=edge”>
<meta name=“viewport” content=“width=device-width, initial-scale=1”>
<!– The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags –>
<meta name=“description” content=“”>
<meta name=“author” content=“”>
<link rel=“icon” href=“${webRoot}/static/favicon.ico”>
<title>Signin Template for Bootstrap</title>
<!– Bootstrap core CSS –>
<link href=“${webRoot}/static/css/bootstrap/bootstrap.min.css” rel=“stylesheet”>
<!– IE10 viewport hack for Surface/desktop Windows 8 bug –>
<link href=“${webRoot}/static/css/bootstrap/ie10-viewport-bug-workaround.css” rel=“stylesheet”>
<!– Custom styles for this template –>
<link href=“${webRoot}/static/css/custom/signin.css” rel=“stylesheet”>
<!– Just for debugging purposes. Don’t actually copy these 2 lines! –>
<!–[if lt IE 9]><script src=”../../assets/js/ie8-responsive-file-warning.js”></script><![endif]–>
<script src=“${webRoot}/static/js/bootstrap/ie-emulation-modes-warning.js”></script>
<!– HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries –>
<!–[if lt IE 9]>
<script src=“${webRoot}/static/js/bootstrap/html5shiv.min.js”></script>
<script src=“${webRoot}/static/js/bootstrap/respond.min.js”></script>
<![endif]–>
</head>
<body>
<div class=“container”>
<form class=“form-signin”>
<h2 class=“form-signin-heading”>小温之家</h2>
<label for=“inputEmail” class=“sr-only”>Email address</label>
<input type=“email” id=“inputEmail” class=“form-control” placeholder=“Email address” required autofocus>
<label for=“inputPassword” class=“sr-only”>Password</label>
<input type=“password” id=“inputPassword” class=“form-control” placeholder=“Password” required>
<div class=“checkbox”>
<label>
<input type=“checkbox” value=“remember-me”> 记住密码
</label>
</div>
<button class=“btn btn-lg btn-primary btn-block” type=“submit”>登 录</button>
</form>
</div> <!– /container –>
<!– IE10 viewport hack for Surface/desktop Windows 8 bug –>
<script src=“${webRoot}/static/js/bootstrap/ie10-viewport-bug-workaround.js”></script>
</body>
</html>
启动成功，访问却报错：ServletException: Circular view path。。。Check your ViewResolver setup。。。
我依赖添加了啊，为什么没有加载freemarker，找不到视图渲染？配置有错？视图解析器有问题？mvn clean install下，还是一样，jar包里有FreeMarkerAutoConfiguration类啊，不是说会自动加载freemarker类吗？包冲突了，启动也没看到freemarker 配置日志？不至于啊，springboot的依赖配置不是模块化了吗？不至于吧，然后我把spring-boot-starter-parent父组件版本 ，有1.5.4改成1.5.3，他就好了。。。Springboot能简单快速开发是好事，可以一出问题就坑了。不懂得原理就会成为硬伤。暂且这样吧。。。
