Spring RESTful 配置问题

浏览数：16 / 时间：2015年06月08日

1.restful模板默认不显示id字段的，可以参考http://tommyziegler.com/how-to-expose-the-resourceid-with-spring-data-rest/

添加id字段。

2.spring boot 下jsp 404不能正常显示的问题。参见: http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-jsp-limitations

26.3.4 JSP limitations

When running a Spring Boot application that uses an embedded servlet container (and is packaged as an executable archive), there are some limitations in the JSP support.

With Tomcat it should work if you use war packaging, i.e. an executable war will work, and will also be deployable to a standard container (not limited to, but including Tomcat). An executable jar will not work because of a hard coded file pattern in Tomcat.
Jetty does not currently work as an embedded container with JSPs.
Undertow does not support JSPs.

There is a JSP sample so you can see how to set things up.

3.访问不到静态资源.

在servlet的配置文件中，修改

<mvc:resources mapping="/static/**" location="/static"/>

为

<mvc:resources mapping="/static/**" location="/static/"/>

3.上传文件

在servlet的配置文件中添加

 <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

程序会陷入循环，一直加载。在pom中添加相应的库

        <!-- Apache Commons FileUpload -->
        <dependency>
            <groupId>commons-fileupload</groupId>
            <artifactId>commons-fileupload</artifactId>
            <version>1.3.1</version>
        </dependency>

问题解决。

4.Spring Jpa + hibernate + Spring boot 简单配置即刻访问数据库，获取数据，但是却无法保存。

原因没有添加事物管理，在pom中加入：

        <!--Transaction-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
        </dependency>
        <!--Transaction end-->

在启动时加入资源:

@SpringBootApplication // same as @Configuration @EnableAutoConfiguration @ComponentScan
@ImportResource("classpath:config.xml")
public class Application extends SpringBootServletInitializer{
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(Application.class, args);

        System.out.println("Let‘s inspect the beans provided by Spring Boot:");

        String[] beanNames = ctx.getBeanDefinitionNames();
        Arrays.sort(beanNames);
        for (String beanName : beanNames) {
            System.out.println(beanName);
        }
    }
}

配置/resource/config.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"

        >
